My ex have been broken up for quite sometime and we occasionally talk and recently he messaged me on facebook asking if I would participate in a threesome. He already has a partner and they have been dating for 2 months and quite frankly I never knew she would be up for this since she is madly in love with him so imagine my surprise when he asks me if I would like to have a threesome. I haven't had a good shag in over 2 months so I am kinda considering it but doesn't having sex with one ex lover and a new flame complicate things? I know it is every man's fantasy to have a threesome but why would he ask me when he already has a partner? Isn't having sex with one partner good enough why involve me? Perspectives from males or females please thank you.
