Not doing it right 😱?

Me and my boyfriend have been trying to have sex for a while. It hurts every time, which is why we never go all the way. I always tell him to stop. I don't know if something is wrong with me, I obviously have to be putting it in the correct hole but it hurts everytime. It doesn't seem to be getting any better. Maybe it's because every time we try to have sex, it's like weeks, days and this last time, months apart. I don't know but last night, we had sex and I bled a little bit. It was a little lighter than red, it was pinkish kind of.  I don't think my hymen stretched or whatever because I probably would have felt it and the sex would've felt better, but it didn't. I know, I sound crazy and I'm talking all over the place but I don't know what's wrong with me. Please help me!Â
