My boyfriend is reallllllyyyyyy into anal and I’m into whatever makes him feel good so I let him do it. However he wants to try it without a condom and I’m not sure how to feel about that. We’re both negative for stds so that’s not a concern but I do know that if any semen gets near the vag there’s pregnancy potential. Is there something I can do to prevent this from happening. Also I’ll be about 4 days out from my period so do I even need to worry? Someone pls help me out!
