How to make sex less painful with a big partner?
I desperately need advice on how to make sex less painful.
My (20f) boyfriend (23m) and I have been dating for 3 months and he's the first person I've been with, he's also very big.
Everytime we have sex I feel like I'm getting torn, similar to the pain when losing your virginity. Only after 5 minutes or so do I stop feeling like I'm tearing.
He takes a lot of time to finish- it could be an hour of him inside before he does which makes me really sore and I end up slightly wounded needing a couple of days to heal up until we can do it again.
I don't really get wet so we always use lube but it also doesn't help, and because of the pain sex doesn't feel good to me at all, it just alternates between painful and not feeling anything.
I don't know why it's like this because we do foreplay he always gives me oral before we do it.
We also tried many different positions so that's not the problem either.
I really want to stop dreading sex and learn to enjoy it so I want to ask if anyone went through something similar maybe and did it get better?
