He got upset because these so-called friends of yours would fuck you faster than an F-16 if you gave them the opportunity.

Your boyfriend, being a man, knows what these other men really want when you dangle your goods in front them like a piece of meat. "Socialization" with the opposite sex is a euphemism for flirting.

Allowing these other men to shower you with their subconscious sexual affections makes your boyfriend feel as though he's not satisfying you.

It makes your boyfriend feel like less of a man if you are constantly seeking the company of other men to keep yourself "happy".

If you want to be a socialite for pleasure, stay single.
