You would really have to do more research.
If you're pitching to a cable network (ABC, CW, etc), then I'm most certain the love scene couldn't go too far. Would have to be like fade to black type of thing, or kiss and that's it, since they're not pay channels such as HBO or SHO.
A couple of weeks ago I ran into a list with the top TV networks for LGBT characters. Wish I could find that list. It wasn't Wiki, but there are a couple of lists on Wiki, too.
