So I just had sex for the first time today. We didn't use a condom at first but he pulled out about a minute before he was going to cum. He came on my stomach and then asked if we could go again. I said yes but we have to use a condom this time. We did and during the whole thing it ended up ripping and we didn't know. He didn't cum a second time but I'm worried there could still have been some from the first time. Is it a possibility I could get pregnant? I know sperm can still live in the penis even after coming so that's why I'm worried some might have gone in.
