Blowjobs Vs Sex

So my bf and I have been together for eight months now but we haven't had sex yet. I mean, we're very intimate, he loves receiving oral so that's what we do exclusively but I'm wondering if I should be pushing for PIV sex?

It started because I'm a bigger girl, not huge but I think I'm a bbw. And I have a hard time getting naked around anybody. He's really fit and that's one of the things i find irresistible about him. I want to be like him one day. I'm trying to learn from him but right now I'm just not able to relax enough to enjoy being naked with a partner. He's been great at respecting this. I was honest with him about it and he could tell that I was very self conscious so he suggested that I keep my clothes on and I could just go down on him. I'm really thankful that he's okay with my taking it slow and not being pushy but honestly I thought that he would just have done it by now and I would have given in and let him have sex with me. But instead we're eight months in and we're still at the blowjob stage.

I love giving him head and he seems perfectly content. It is just that I thought most guys would want sex by now and I'm wondering if he doesn't see me like that? He said a while back that he loves doing blowjobs with me (or he calls it face fucking?) much more than the sex he used to have. He said that he didn't know there are girls like me and that he's never going back. I just thought it was bedroom talk not how he actually felt. We both like the fact that I don't need to worry about birth control or what time of the month it is. I still tell him when my period starts (just in case) but he just smiles.

I actually love doing oral, it makes me feel extra submissive. Also, I had no idea before about all the positions that are possible for oral and I get excited when he starts taking his belt off or when he tells me to kneel. He's the first guy I've swallowed for and now i look forward to it everytime. I assume I would learn how to enjoy sex eventually too but right now I have a hard time imagining being able to satisfy him the same way and that would just make it even harder for me to enjoy it.

Should I bring this up to him? I feel selfish for making him so something different than what he likes and I still feel self conscious about having sex so maybe I should just let it happen. I feel like I'm falling in love with him and I don't want to mess it up. He is kind to me and treats me great outside of the bedroom. I really don't mind sticking to blowjobs but I just thought he'd push for more by now. What do you think? Has anyone been in my situation? How long were you in the blowjob stage?
