My friend and I were messing around one day and he rubbed his penis against my clitoris and he put it at the edge of my vagina literally no further than the edge.... I'm a virgin so he didn't go any further than just the edge... He did not cum cause we had to stop cause something come up...all I seen was precum and he did urinate before we did anything....and several times that day... He did not cum....just the precum.....if there was no cum just precum...would there be any semen present and would there be any chance I could get pregnant
