How Long To Wait Before Bringing Up Exclusivity?

I recently met a guy that I like a great deal. He’s super good-looking, a great conversationalist, and an all-around sweet, caring, and attentive guy. He’s quite a catch.

Tomorrow we’ll have known each other for a month. In the time that we’ve known each other, we’ve spent time together on 11 separate occasions, not including the mornings/afternooons after spending the night at each others houses, of which there have been 5. Most of those have been genuine dates, where we’ll go out for walks, get dinner, enjoy some live music. Other times he’s just invited me to come see his band perform and then spent the rest of the night when wasn’t on stage stuck to me like glue.

He’s met my closest friend and my younger brother this past week, and I’ve met his best friends and some other people close to him. He’s talked about me to his mentor (his band’s producer) and his dad, as far as he’s told me.

We’ve slept together a handful of times, but not until date #4. He’d spent the night after date #3 but our clothes stayed on and we just talked until the sun came up.

He always initiates texts and calls and plans our get-togethers. My younger brother and I were doing the math and it turns out that he and I have statistically seen each other more than 1 out of every 2 days in the last month. I’ve literally never called him, but we talk on the phone nearly every day, and that’s along with multiple texts per day.

I can tell he really likes me, he’s a great listener, he asks me questions and follow-up questions and so on. He always smiles around me, he’s SUPER affectionate and touchy-feely. We’ve got great chemistry, can talk for hours. Even when we argue (usually about music) it’s good-natured and we really enjoy ourselves. The last time we argued it was over styles of lyricism and it lasted for about an hour and a half but while we were vehemently opposed in opinion, we were both laughing and smiling throughout the debate.

Anyway,
I’m wondering when would be a good time to initiate the “Exclusivity” talk. I’m not necessarily to the point where I “need” us to be a girlfriend/boyfriend couple. I’m not clingy or needy at all, I give him space, I rarely initiate texts and I haven’t once suggested that we hang out, that’s all been him. But aside from one conversation early on, the morning after we first slept together, wherein he asked me what I’m looking for in a boyfriend (and pointed out after every item on my list that he possessed each of the qualities I’d described) and then pretty much described me to a “T” when I in turn asked him what he was looking for, and then made a point to acknowledge that I “fit the bill” so far.

I told him that for now I’m really enjoying being single, because until this point in my life, I’ve been a serial monogamist and I haven’t been single for longer than a couple of months since I was 16 years old. All of my relationships have lasted between 2 and 4 years, so I’m enjoying this period of freedom and self-reflection. He said he understood and really liked that I wasn’t aching to be in a relationship, and that if I decided that I wasn’t feeling the whole “us” thing with him, that I should feel free to let him know that I wanted to call things off and continue living/enjoying the single life, that he’d totally understand. I said “Absolutely, and same goes for you!”

Aside from that conversation, we haven’t brought up exclusivity and on top of that, at each of his shows that I’ve been to, he’s introduced me as just “My friend, Sherridan” to everyone. A couple of nights ago, I brought my brother with me to their show, and he really engaged with him, asked my brother a lot of questions about himself, and was quite affectionate with me around him and his bandmates as well as his best friends that he’d just an hour before introduced me to as his “friend.”

He had his arm around me all night, held my hand, and toward the end of the showcase, he pulled me close to him and we slow-danced while he kissed my forehead and rubbed my back. He didn’t let me go all night, even when his friends came up to talk to him, he always had a hand on me. When he’d go to get water or use the restroom, I’d gravitate toward my brother and interact with him, and the second “my guy” would come back, he’d reach out and put his arm around me and pull me back into his embrace.

When my brother was leaving the venue,they shook hands, and “my guy” says to him “Thank you so much for coming out! I’m sure I’ll be seeing much more of you!” With a huge smile.

He then took me home and on the way home suggested that we spend his birthday together at my place. I was receptive to the idea but didn’t say much about it. The next day, which was yesterday, he called me on his way home and again suggested that we spend his birthday together at my place “if nothing else comes up.”
When I sent him a text saying “Happy Birthday!” He thanked me and then asked “Should I just head over to your place after work, then?”

So again, he definitely loves spending time with me. He’s very affectionate and shows a lot of PDA with me, we have insane chemistry, our conversations are never-ending, and he’s totally comfortable with being around my family and closest friends already, as well as introducing me to the important people in his own life and being quite affectionate with me in front of them. He even came over to my house after work once just to drop by and give me a backrub and catch up on my day/week for an hour or so before he rushed home for band practice.

*BUT*

He introduces me as his friend every single time I meet someone in his life. He hasn’t brought up exclusivity. I told him once while we were cuddling late one night that I don’t feel comfortable having sex with him without a condom if we aren’t at least practicing “Sexclusivity” even though I’m on birth control, and while that was a great opening for him to step in and say he wanted us to be exclusive and monogamous, he actually just said “That makes sense, I totally understand and respect that,” And fell right to sleep. We never talked about it again.

SO my question is, when should I bring it up? His birthday is today and I’m making him a big dinner. Obviously I’m not going to bring it up today. But when? I know it hasn’t even been a month yet, but I really like him. As far as he knows, I’m seeing other guys (I hang out with my male friends very often when he and I aren’t together, and they tag me in things on FB all the time, and he “likes” the statuses, so I know he sees them. He’s even asked me how such-and-such event went and “did you guys have fun?”) which I’m not, and as far as I know, he’s seeing other girls, though I doubt he’s had the time, since he’s literally always practicing for his band or at work or playing a show when we aren’t together.

I’d like to be exclusive with him eventually. He’s an amazing guy and I feel great around him. I don’t mind not being in a relationship, I do quite enjoy being single, and honestly while I’d be SUPER bummed if he and I called it off, I’d definitely be okay.

Should I wait for him to bring it up? Should I say something first? How soon is too soon?
