none of those 'relationships' meant anything to me 🙄

None

3
one lasted 4/5 years, another 2/3 years and other 21 years

If you include both serious ones & FWB ones, it’s been about 15.

Many when I was younger, none in the last few years.

I'd ruin my reputation if I told you

Been in a relationship with someone basically since I was 13. Longest was 2 years, shortest was 6 months.
Two or three were more casual and lasted at least 2 months.

four serious ones... but not by choice. Only wanted one lasting one!

I can't fathom the total number of relationships I've had in my life.
If you mean romantic/sexual relationships, then it's 27.

Shut up, Andrew, I'm single now and that's all that matters.

If you mean sexually based, two (1+3/4+1/4)

numerous casual ones and two serious relationships

5, shortest was 1.5 year and longest was 4 years

one

Can I plead the fifth?
