Oh! Maybe this is a good enough place as any to gather some insight on this matter.
And please believe me, I don't mean to offend anyone here. Just genuine curiosity.
I'm a straight guy. And as far as I know, all my straight guy friends don't think it's a big deal if girls we're currently not connected with get some experience with fellow girls for whatever reason. Say if the girl was a virgin and then she gets together with another girl, most of us would still think she remains a virgin. Is that thought offensive?
And to be clear, "virgin" here means figuratively and not necessarily the hymen getting popped.
