The only three possible answers you will receive:
3. Actual straight men who have no sexual interest in dicks or other men and who even if they weren't getting any desired sex or sexual act with their current female partner would simply go seek it with another woman before they would ever consider another guy (which would not make it any more or less morally wrong), because to them, at the end of the day the mouth is still attached to a dude and therefore not the same.
With the third group (which are the only ones who are allowed to and should be answering in this thread),
one should except a steady response of "No", "Hell No!" or mildly sarcastic memes or GIFs to what to is by now a well-worn subject.
