Long story short, I was messing around with my girlfiend on my bed...she started to give me a hand job (and as any guy knows, if you get excited enough you tend to "leak" a little bit even if you don't actually have a full orgasm or ejaculate) and I stopped her before I did, just because I didn't wanna make a mess in my pants and on my bed...but I reached into my pants to "rearrange and fix" myself and I got some sperm/pre-ejaculatory juices on my hand. And then without thinking, I started to feel her vagina and finger her with the same hand. I know...really stupid. Now I'm freaking out that even though we didn't actually have sex, what if somehow she still got pregnant from what was on my hand and fingers touching her...? It was 2-3 days after her period, if it helps. Is that even a possible? I know this is a really dumb question and it may not even be realistic, but I'm still pretty paranoid, none the less.
