Sex life going down

I have sex just to please my boyfriend, at this point. It doesn’t feel good at all. It’s kinda painful especially if I’m dry. And we just had sex 3 days in a row and the 3rd day I was so dry. He asked me if I was unattracted to him because I was so dry. But at the same time my vagina was sore from the last two days.

He told me about other girls he’s been with how they just squirt for him. So it made me feel bad. Although I never squirted I just want to know what’s wrong with me.

It doesn’t even feel good to get my nipples sucked on.

I want to feel good and I want him to know I feel good.

Any tips?
