Well, my girlfriend and I are abstaining from sex, at least for a while I think, although we do fool around and with stimulate each other manually. A couple times we have done this were she is in her underwear and I am without, I'm not certain the ammount of my cum that may have come into contact with her panties, although I don't think it was much from the position and the ammount I found on the bed.
I was wondering to what risk someone would be with semen on the outside of their underwear? I am aware that it can seep through some fabrics, but are the chances of this very unlikely? In addition she had her period about a week ago, i'm not exactly famliar with the menstrual cycle in relation to fertility but does that dimish the chances even more?
I think i'm going to avoid this kind of situation where I can get my fluids on her panties, just in case, although I would like to know if i shouldn't worry about what has already happened. Thank you for any responses.
