Assuming everyone involved is known to be clean.
Personally, i would prefer my partners not to have had sex with anybody i know before me
so you would rather have sloppy's with a girl who just got fucked by a stranger?
well, in eveolutionary terms
penis's are shaped they way they are, with the head and the hood thing at the base of the head, is so that it can scrape out the ejaculate of the previous male that has been in there as you thrust in and out
I don't even like my own cum, let alone some other guy's.:throwup:
