Sex hurting?

Okay so to give you the background, me and my so used to regularly have sex, we went 2 weeks without sex, Friday we had sex again for the first time in those two weeks, he said i was very tight and i noticed it hurt as he went in but after he was in it was fine, i noticed tampons hurt going in too. Is it just because i went two weeks without anything going in there or? I had lab drawn not even two weeks ago at the drs for a std check and everything else so i dont think that's it if something is wrong...
