is it normal to bleed during sex?

i’ve been dating my boyfriend for a few months now and i was never really into sex or anything before we met, i enjoy when he and i have sex but often it’s somewhat painful for him to put it in no matter how turned on i am AND when i go to clean up after i can see pink in the tp. im not overly experienced in any of this but i don’t think it’s normal? and i can’t ask my mom bc she isn’t around to ask anymore so im hoping for answers (im 20 btw if that matters at all)
