Semen is all protein. That's what I told an ex-GF. She wasn't convinced initially but I said if it was coming from within me, it can't be poison rite? Else I'll be dead already. That convinced her to swallow
The downside was she would move in for a smooch after the act and I'll be pushing her away
Hell, if I wanted to taste cum, I'll be a f**kin' faggot.
