Inconsistent pleasure when having sex

My boyfriend and I have a p big size difference between us as far as our equipment goes. I am typically very, very tight and he is about 8in erect.

It takes a lot for me to come/orgasm generally, and with him sex kinda just, is uncomfortable. It has the potential to feel good, or rather, it feels good, but there's also a level of discomfort- but it doesn't hurt. Sometimes when he goes to deep and hits my cervix, yeah that hurts, but sometimes I don't feel anything. Sometimes I can take all of him and it feels good, but most of the time it just feels uncomfortable. We switch between missionary, doggy, and one where I'm on my stomach with one leg stretched out (idk names in sorry). The last one feels the best, yet that uncomfortable feeling is still there like he's constantly hitting something. I ride him occasionally, and that feels okay, but again, the uncomfortable feeling is still there, just not so badly bc of the angle I guess.

He likes it rough, and I like it passionate, so we're working on a balance between the two. (I like it rough too, but bc it just feel uncomfortable, as of late I've only ever enjoyed when he goes really slow.)

I've only had one other partner before him who I believe was something like 5-6in, and sex felt amazing. I never I had the size issue. But prior to my new man, I hadn't had sex for more than a few months and it took about 7-8 times to truly break me in. With my last partner I lost my virginity to him and it took about 4-5 times before sex felt good. I understand that bc I'm working from a v small sample size I don't have much to really make concrete observations from.

Another thing I've noticed is that I don't really stay wet for very long. With both of my partners I've needed lube.

I think that in general we need to spend more time getting me turned on and loosened up, but other than that the inconsistency thing is really inconvenient because it can be the same position but feel different each time we do it. I can't get a good read on what works and what doesn't, but at this point right now, I can't really say I can enjoy sex and it sucks.

I'm speaking to a gyno in April, but I wanted to know if anyone had any tips for me.
