Help needed

[Brian738]

So, umm, i am 16, a bi, and i have a gf. she is the best person in the world. she doesn't mind or care if at least once a month i do things with boys (mostly sucking and jerking) and that's why i love more that anything else. but lately, while we'r having sex she has asked me to do rather strange things to her (punch her boobs, tie her and whip her with a belt, urinate on her, bite her vagina, stuff a cum-soaked sock in her mouth and hit her face with my erected penis), now, i also have my "fantasies and all (one includes a belt), but this is a little too much. talking to her did no good, she slightly worries me. What should I do? (i am great at helping others, but i can't help myself)

Your girlfriend is into BDSM, [an overlapping abbrevation of Bondage and Discipline (BD), Dominance and Submission (DS), Sadism and Masochism (SM)]. Are you comfortable with how she wants to have sex or are you worried that you're hurting her?

As John said it appears she definitely is into BDSM.
If you don't feel comfortable with it I suggest you just talk to her about the situation. That's all you can really do.

John is right on
if you are not comfortable with doing that stuff and she wants you to, it may be time to think about breaking up. if you can work something out then though that's great
