Oh yes, I am getting up to speed very quickly. It becomes more obvious the older a person is who has never been married or had many serious LTRs.

Alright so you're 49 and your longest relationship was less than 4 years?

40. And my longest exclusive relationship was five years.
But I see a big FAIL on my report card coming.

Everyone over 30 has baggage. A lack of LTRs could be just the history one person looks for, while past LTRs might be important to another, and LTR history may not matter a damn to a third. Depends on what one is seeking. Even then the personal connection, or lack of it, is the real decider. There's no report card.

It depends on what else they were doing with their life. A Nobel prize, or walk on the Moon, would be justification.

Sex addict. Could be a plus?
