I would not be asking an mpa how to have sex. Go see an escort instead.
Not all MPA’s will even offer sex. Some that do might only want to get paid so they just want you to get in, get off and leave. Some might charge you more to teach you.
If you want to know how to have sex, your high school sex education course should have given you the basics. Beyond that, learn to control your orgasm so you can last longer. Women take longer to get off than an average man. Pay attention to what she likes and doesn’t like and adjust your technique accordingly. She might not tell you what she likes so pay attention to her body language, signals and moans. If you focus on her pleasure first, and she enjoys herself and gets off, then you have learned how to have sex. Until then, you are still an amateur, at least in her eyes that is.
