I have a small window of opportunity to (maybe) visit a sex party when I’m next in London (I rarely get such opportunities). However the only fly in the ointment is that I’ll have to meet up with the wife, literally 10mins after it ends. Obviously I’ll shower at the end of the party, but I’m slightly paranoid she’ll smell the perfume/scent. Am I being a bit paranoid or is it a valid concern? Any thoughts?
I see many things wrong with your post. You asked for it...
An opportunity is just that, it can't be a maybe.
The expression is "a fly in the ointment", qualifying it as only is incorrect.
10 minutes cannot be figurative.
It's not obvious that you will shower, you mean "of course".
You're not slightly paranoid, you see a risk that she will smell the perfume.
You're not concerned, you're afraid of being find out.
erm... what did you ask me again?
Oh yes - you're a heartless prick and stupid to boot.
(Please don't take offence, just pulling your leg)
