Pain during sex

I have had my third time penetrative sex today. I tried to be aroused and everything, I watched porno, he also tried to arouse me with playing on my nipples and clitoris, but still it hurts when he gets into me, i do not feel the same way when I do some fingering on my own.

I have the feeling I spoil things, I don’t even talk about orgasm, he also feels it and he cannot continue intercourse long enough and fast enough since he feels he hurts me.

I tried to be on top but it didn’t work, I couldn’t let his penis go into my vagina.

Please help me, I have heard of lubricant and everything. I don’t think I am nervous or am I?

He attracts me and I want him, though cannot under what is wrong with me?

It’s me since he had a number of women before me
