So my boyfriend jerked off with his left hand at his house 2-4 hours before he came over and fingered me with his right hand. Now his right hand might have touched the semen when he wiped it with tissue and he didn't wash his hands with soap (yes, i know, gross, but please don't judge), he only washed them with water. But I shouldn't be worried, right? Sperm should be dead by that time? (Also even IF he didn't wash his hands, sperm should still be dead no?)
