Yes. Just like bra and bikini.

Not for me. I know a lot are more comfortable to experimental with other partners.

Yes.

In some ways, generally yes. But of course the dynamic depends on the people in the relationship more than whether they are gay or straight.

Besides the fact that they are featuring different genders or?

You're going to have to be more specific, because I can spot some obvious differences.

Yes.

Most straight relationships are based on gender roles. The man makes the money, the woman raises the kids, the man drives the car, the man pays for dinner, etc..

This doesn't really happen in same sex relationships.

You need to be more specific

I think so. Well, the relationship can either succeed or suck just like any relationship between straight couples.

Yes.

Same-sex divorce rate are lower than heterosexual couples

No, but lots of guys I know will be the first to claim they are different as an excuse to be non-monogamous There's nothing about being gay that inherently makes sleeping around any more okay than for a straight person to do it.
