The allure of the straight boy

[frequent]

Can I ask how you know the boy you off is straight ? You ask him? Or you assume it by just looking at him and his manners?
I rarely ask the boy. I assume they are gay. I don't really care as long as they do as promised. But it looks some of us ask a boy everytime what their sexuality is, how else so they know ?

My favourite anecdote on the subject (from 1988) - a waiter at Telephone Bar who said "I not a gay boy. What time I come your room?". In those days "gay" simply meant "someone who bottoms"
