Suggest Remedy For Bleeding After Intercourse

Recently i started having sex with my bf... im23yo.... first time it hurt, but my partner was very understanding and supportive... he was not a virgin as i so he was explaining me everything....i didnt enjoy it at all, though....
i was bleeding... i also understood way...
but from that time we had sex like 20 times and i never enjoyed it... after every time im bleeding a little bit. today, two days after we had sex last time, i was bleeding when i went to the bathroom... it was a little bit too much so i thought that my period just started 1 week be4... but no... later the bleeding stopped....

Why im still bleeding? Why i do not enjoy sex at all even now when it does not hurt? I love my partner and i see myself marrying him so... why/ i dont want to dissappoint him because i know that he likes sex and he wants to satisfy me, but now even he have noticed that i dont like sex....i told him that no i like it, but it was not true...
