Maybe not a normal question but to me it's anything to do with my first relationship. It's come up many times in different ways.
I was on a Hen do and we were playing games and it was 'whoever lost their virginity the latest has to take a shot'
It was me, I was 19 and it wasn't consensual. It was an abusive relationship. So I don't know whether to count that or the sleazy boyfriend I had right after aged 20.
It comes up very occasionally 'have you ever dated a scotsman?" Yes, my abuser but I can't say that so I just lied and said no.
"How old were you when you had your first relationship?" again the dreaded question.
I asked a lady who was telling me about her son the other day how many kids she had. She told me that just one as her other had died.
