Im a virgin and my bf and I try having a "semi-sex" meaning that his penis is not all the way inside my vagina, just the tip and some of its skin. Just b4 we do the deed, he urinates and wipes off his precum. He came outside while I was bj'ing him, he then go to the bathroom to clean his junk, he washed it with water. He is not sure if he urinated that time tho.After the cleaning, we cuddled for a few minutes, his penis is still hard and all so we decided to do it again.. the "semi sex." Is it possible that another precum that has sperm came out inside my vagina the second time we did it? And if there is, can it reach the womb even tho his penis is not all the way inside? How about my hymen? I didn't bleed tho, does it mean that it didn't break? Can the sperm pass through it? It's been a week after my menstruation ended when we did "it"and im worried if im on my fertility stage.
