Am I stupid for being bothered by this?

By bf and I have been together only a few months and we’re 22 for reference (both turning 23 this year)

He doesn’t like hearing about my dating past and I don’t like hearing about his. We’ve briefly discussed it, like how many serious relationships and body count. Neither of us cared bc it’s in the past but idk it just came up one night

Anyway. There’s little things here and there that my bf says that make me feel so bad

He said the way we do a couple positions when having sex are different than how other girls he’s slept with have done them (he’s slept w around 20-30 girls, I’ve slept with 7 guys). He says they’re unorthodox. And the positions the way I do them are how I learnt them from other guys. I don’t watch porn. It makes me feel so dumb and inexperienced. Makes me not wanna have sex with him.

He also said I’m hard to figure out sexually and that I’m unique. And that my vagina is different than what he’s used to because I have bigger lips. I don’t wanna hear this. Idc if he comments on my body bc he wasn’t saying anything bad, said he loves it. But I just feel compared even tho he said he’s not comparing me but obviously his knowledge came from somewhere. Which I know and obviously my sexual knowledge came from past experiences too. But I’m not out here saying I’m confused about what he likes and what he doesn’t because it’s different than other guys.

Another thing - the other day when we were getting dressed, I had a super soft underwear on and one side of the cheeks was tucked in and I didn’t notice bc it was such light material. And he fixed it which was good with me, but then he said “how do you girls never notice that”. I hated the “you girls” comment. I didn’t even process it properly until later so I have yet to talk to him about it.

I KNOW he doesn’t mean to do it. I know that. But I hate hate hate hearing it. If I did the reverse he’d be so upset. And I’m not going to because I’m not petty like that. I will talk to him when I see him next bc in the moment when it happened I just didn’t process it properly.

I wanted opinions from you guys first. There’s other comments he’s made similar to that but those are from the last couple times I saw him.

Am I wrong for feeling hurt and annoyed?

I know I have no right to compare to his past and he’s with me for a reason etc. but it doesn’t make my feelings better, I can’t always control my emotions.

If you guys think I’m overreacting then tell me please so I can rationalize with myself instead of bringing it up to him
