Possible Gay husband!!!!?

My friends husband is from a place where they are supposed to be chaste until marriage. After they married the was well...new and quick, after two years it is still quick, he refuses to explore her body or even really touch, is in and out, no and his comment to her unable to climax" that is your problem, he feels a womens are disgusting! He does however like to look at on the net in secret. Is he gay? Not into her? or maybe both?
