This is completely false. A sex worker is paid to get you off and cater to you what you want within boundaries. For your gf or wife to give you exceptional sex, her interest level has to be high atm and that takes maintenance and depending on what mood she is in that night. For example, I can go see my therapist and then go home and cook myself a nice steak and chill on the couch playing PS5 with an old fashioned whiskey VS a GF is not going to leave your place most likely and make you watch some dumb show on Netflix, make you take her to some stupid Fair and family dinner killing your whole Sunday, and then be in some unpredictable period moon swing mode for the next 5 days of the workweek.
Any guy that chooses the GF option has never dealt with this BS before and hasn't learned to love & appreciate himself because you can have plenty of toxic relationships with women but if you do not love yourself then you will always want to go back to another one.
