so today i had sex, lots of sex, like 3 hours of sex. my boyfriend was at a music program for 6 weeks so when we finally got to see eachother we went a little crazy ( our relationship is not all about sex, we are very in love and have been for over a year now ) 
it was really rough sex, i gave him a bj and he came, we went out to eat (chinese, it was yummy!!) and then we came back about an hour or two later and started to have sex, it felt so good and we both really enjoyed it. he did not cum inside of me, i'm on the nuvaring (i love it, i've never had any problems with it) but i always get paranoid, i have really bad anxiety so i always think awful thoughts, also i'm really sore, really, really sore i drew a little star where its hurting, it's always been sensitive but i guess i'm just looking for reassurance that i am okay, in the past my vagina has ripped (WORST THING EVER) 
i always get very scared so please give me tips on how to make the pain go away
