The reason I have stayed single for 30 years is because I met men that I very much liked, same sense of humour as myself, intelligent, kind, etc., but I didn't feel sexually attracted to them. Then I met a few men with whom I fell in lust but realised I didn't actually like them. Eventually, I gave up!
(My husband of 19 years was terminally boring - I only stayed with him so long because I quite liked him and didn't want to hurt him. I needn't have worried, he was remarried within the year!)
