What do you think of guy to guy relationships? or girl to girl relationships?

its out of normal human behiviour.. we have bean created in pair.. woman with man

You see this more and more with celebrities. I think that it is getting more well know. As for being accepted, everyone has their own opinion. If your friends are going to change their relationships becuase of the image it projects, maybe they need to evaluate why they are really in this relationship.

people who engage in same gender relationship have nature-nurture issues, resolved or not. this is not normal in some countries, but is accepted in some. as for me, this really is not a big deal nor a problem. i believe in individuality and freedom. it's only the "self" who knows the real source of happiness, not any external force. for as long as being in a same gender relationship does not inflect pain unto others, go for it!

from the view of the society its not accepted. but in some western countries its been legalised...

I actually have friends who are gay. It's actually alright for me to see them with the same gender because that's what makes them happy. I really don't care about what the rest of the society think about them. I guess everybody should just mind their own business.
