Its not even the sex... I can go months without that.. its the lack of contact. Life can be tough enough but when you find all you are doing is going to work, coming home alone to an empty apartment, cooking dinner, watching tv.. bed... then the same thing the next day... life begins to lose purpose. Wish I had some mates to hang out with at the weekends.. cinema, coffee meets.. etc
Ozren has given some good ideas above if you are looking for lgbt friends. I find the wet and wild group on meetup.com a really great group.
