Sexless relationship

So…

I (32m) been dating a guy (26m) for about 6 months now. We had an odd break (traveling) for about 2 months about 2 months into our relationship but talked everyday during that time and I was not worried about him sleeping around, as I told him he should do so if he got the chance.

Anyways, before he left, we had had some sexually intimate moments, but since he’s been back I’ve only seen him naked once, about 2 months after he came back. We’re still very much so personally involved, and still text every day and see each other 4-6 days a week too. I really like him, a lot, but the lack of sexual intimacy is concerning me. I don’t think he’s sleeping around, and neither have I, but the lack of sexual intimacy has been bothering me.

I’m fit and he’s not so much (and I don’t care at all), and I feel like some of this may be due to him feeling inadequate. The issue is I don’t know how to bring it up. I don’t wanna make him think that sex or sexual intimacy is all I’m interested in, but I do definitely think it’s important (if not integral) to a relationship that I want to be a part of.

Here is the issue: I want to bring this up but I don’t want to do it when we’re hanging out, just us, because I don’t want him to feel pressured, but really the only other time right now that we hang out is at the gym.

I’m thinking about bringing it up at the gym, probably when we’re done and full of endorphins- and honestly not too worried about that.

I’m more worried that I’m pouring time into a relationship that will eventually be looked back as a friendship. Although we don’t use labels, I’m getting more so the feeling that we’re an old sexless couple that just talks most of the time. So I guess the question is, how do I determine what this is? - besides just straight up asking him. And if he is insecure or unsure about where we are what I can do/say to help us better find out grounding.

Thanks ahead of time to anyone that read through all this garbage ☺️

TL/DR: I’m worried about my sexless relationship.
