You have the right attitude. Make both MM and Spouse/GF happy.
MM wants it done so she could get to the next client.
Spouse/GF wants to come and you will make them happy.
if u r seeing the mm in the afternoon, masturbate in the morning, this will desensitize and prolong the later experience. or just do what i did before, book at least one hour or 90 mins, and have 2 shots, first shot will be like 3 mins, second shot will be at 10 mins plus
