My boyfriend and I have crazy sex drives, so we go for it alll the time. I'm on the pill and we usually use condoms, but yesterday, we ran out after the first time of the day. Later in the day, we had sex twice more, and he pulled out both times, but given that they were consecutive without toweling down first, I'm worried that cum from the first time might be a problem. He penetrated both times, and I just recently learned about sperm staying viable from the last time he came. I'm eighteen and in college, he recently graduated and is working full time now. A kid would be really bad right now, do y'all think I should take Plan B or just let the pill do its thing? I can afford to buy Plan B, but it's tight on a college student's budget, so I don't want to unless it's absolutely necessary.
