This seems like one of the fundamental differences between men and women. Women are much more capable of being strictly platonic than men. Your boyfriend dislikes the idea because he knows well that every one of those male friends who isn't gay or asexual is going to want to fuck you. It doesn't mean that men can't be 'real friends' with you, but the general rule is that whatever the relationship is, he wants to have sex with you.
If you want to know how men would act if they weren't inhibited by women's relative lack of sexual interest, look at gay relationships. It's not unusual for them to have 100 different partners per year.
What do u think about your BF having female friends?
Can u be ok with the fact that him will hangout with one woman, to eat, having fun, putting photo on instagram with her and a beautiful legend like: "special time with my best".
You'll call him to come to your home and he'll answer: "oh, I can't, today I'll in the starbucks with Lisa"
I'm pretty sure no one will like this. I'll be jealous.
A friendship between straight man and straight woman will never be the samen than man-man or woman-woman friendship.
A man go to his friend's bedroom drink, talk, watch some sports and etc, but, a girl will not do the same.
So, one thing is u talk with your friends on the campus other things is you hanging out with them.
