I’ve probably done similar things to @
Guillaine’s guy, frontloading my make-or-break attitudes and needs to avoid getting entangled with someone wrong for me, wasting my time and their time. This includes sex stuff first. I don’t think it was clumsy on my part, though. It was deliberate and direct, but the intent was benevolent and I think that came through.
If a guy asked if I give head, my response would be, how long ago did you break up with the woman who wouldn’t, and is that the only partner you’ve ever had? :/ I would also consider following up by asking why she wouldn’t, and if he bathes frequently, and if he goes down. Et cetera. I’d expect him to go away pretty quickly in response.
