hi Ive been seeing my bf since november and at the start of this year we started to pleasure each other hes gone down on me and used his hands on my clit, Ive used my hand on him. half way through february we went away with friends and when we were in bed together he got on top of me and we were kissing he was gently rubbing his penis against my vagina and id say around a quarter slide inside me but he pulled out. then once we got back it happened again and then the third time we kept going he got it around three inches from completely in but we had to stop as it was really painful then this week we were in bed and he went down on me and then slide himself inside me which was fine but then as he tried to thrust it in further it hurt again but he did get it further in by about a inch afterwards i went to the loo and there was a small amount of blood not much at all , he has tried putting his finger in sometimes he can sometimes i tighten up and he carnt. any ideas on how to relax because this is driving me nuts
