Another thing to take into account is a male client/female T is a slightly different dynamic. If the client is heterosexual and the female T is attractive, sexual feelings can start almost instantly for most men. Even if the female T is a b-itch, us men are more visual and many of us would still have sexual urges.

I don't think a male client should ever even hug a female T if there's sexual feelings involved, especially on the clients side. A female T knowing this and still going for a hug is being unethical.
