The poster says he is willing to go gay for pay, just asking for advice as to whether any other straight guys manage it, and can get erections.
I suggest before you try taking money for it, you have a go, (like we all/some do) with a random for free. I would imagine, as a man, that if you were charging for it, and then backed out the situation might get ugly. Richard or other gay escorts should be able to advise better.
