Relationships for straight people, sex for gays?

Okay, so, my grandpa--the asshole--said this a while ago. And again this morning, that, gays couldn't have a REAL relationship, and the "love" in that is only for sex. My response: Yeah. I'm here. You COULDN'T have had sex. I just popped out of no where. Y'know, I love Robert. I'd say we'd have a relationship, and we def have love. We can't have sex for a while, but, we're still stronger then most straight--or gay--couples. My grandma said that love wasn't all about sex, and I agreed. Just because they don't have sex doesn't mean we can't. Love is love is love. I love him. I have a relationship with him. Can't have sex. So, now, his logic is broken.
