Can a guy really be called straight if he has sex with men?
Of course, and precisely when he shows no
substantial arousal to male visual stimuli (‘targets’).
Sexual
contact is not the same as sexual
orientation. This is where the epidemiological classification comes in.
Examples:
A sex-starved, cash-strapped heterosexual husband comforts himself by performing oral sex on men, or by enjoying their free anal massages (→ BINOs):
MSM = Men who have sex with men
A heterosexual male prostitute bottoms for a client:
MSM = Men who have sex with men
A lesbian prostitute orally satisfies a curious homosexual client who doesn't want his gift voucher to expire:
WSM = Women who have sex with men
MSW = Men who have sex with women
