My boyfriend and I were messing around...I didn't have clothes on but he had boxers on. We started to have sex with his boxers on (he did enter me with his boxers on). He has reassured me that there was no "pre-cum" on him and that while he was inside me with his boxers on he wasn't close to even coming while we were messing around. When he was almost ready to come, I got off him immediately and he pulled the boxers off of him so I know that the boxers were separating the two of us. I am on the pill and I have been for about a year now but the night it happened just happened to be my sugar pills week. He keeps promising me that I couldn't get pregnant, but I guess I need a little more support. I am scared and really nervous, any advice would help. Thank you.
