Do you do dating sites?

Absolutely will not do those

I prefer sites where people can interact via public discussing sections/rooms, over a wide range of topics, organically leading to dating.

Begrudgingly... But I work so much and it seemed like a good way to meet people at first lol

Never have, never will.

Not a chance.

I did...Seems most of the people I met gained a lot of weight and aged about 20 years.

Well I'm going to buck the trend of answers on here and say yes I have and it was very good cumulating in the relationship I have now which has lasted about 15 years. So it was a while back when I last used them i guess they have degenerated since then.
(I did meet a couple of chancers who only wanted sex with multiple people but they soon let it out of the bag.)

No, and no wife or husband

No. They're the worst

Happily married now.

I think dating sites attract the worst of the worst

I have in the past and that a waste of time, currently I’m not dating
