So last night me and my boyfriend had sex, we didn't use a condom but he pulled out perfectly fine. After the first round, we both knew we could go again possibly two more times. So I cleaned him up after each and did. I'm worried about his pre-cum possibly having sperm? and the thought of not knowing if we cleaned up well enough. It was the first time we've done it more than once in once night so this is new to me. I know sperm are microscopic so there is a chance that one of them made it. But I'm afraid to mess up my cycle or harm my body by taking it without need. My bf says he doesn't think I would be pregnant because he pulled out. Should I take it just to be safe? Please let me know what you think!
