I dont think men need more sex than women.
I dont tell my boyfriend bullshit like, dont masturbate when I'm right here.
I want my bf to jerk it some times because
a. it keeps him appreciative of my pussy(not that I need help).
b. I like to walk in on him and help.
c. masturbation is like working it out, and it increases stamina.
It's a natural thing and it's selfish to tell your bf or gf that they cant perform self love if they so desire. You cant cheat with yourself.

now if they masturbate more than they wanna fuck you then it's a problem.
