Constantly needing to know where you are, what your doing and who your with. Then theres the more controlling ones where they practically decide who you can and cant hang out with.. One of my friends does not let him hang out with ANY girls what so ever its actually pathetic.

Let's say the person who is uncomfortable isn't exactly doing that but is actually discussing that concern with their partner? Is that being controlling?

People get jealous every now and then, it's human nature. It depends on how you deal with it.

It's not about the gender but about the person we're talking about

You bring up a good point.

To be honest I wouldn't want him to hang out with other guys because I get really jealous, but I'm definitely not gonna tell him he can't. That's just awful and controlling, I shouldn't be with him if I really don't trust him.
