Hey, so this may seem somewhat ridiculous, but I'm a compulsive worrier, so here goes:
My girlfriend and I were messing around, and she gave me a handjob. I ejaculated, and we both cleaned up the ensuing mess with some tissues. She was completely clothed during all of this, and none of the ejaculate made any actual contact with her. I washed my hands after the cleaning, but she didn't--she said that nothing had gotten on her. A few minutes later, she went to the restroom to urinate. Because she didn't wash her hands, I'm worried that there may have been some sperm on them that she wasn't aware of, and that this sperm may have ended up near the opening to her vagina when she adjusted her pad (she's currently on the 8th day of her period, which in and of itself is irregular for her, but that's beside the point). So is my worrying completely unfounded here, or do I have some reason to be concerned?
