Friends? Sexuality? Rumours? HELP?

It is normal to be confused about your sexuality at your age. Kids often have feelings for the same sex. These feelings sometimes last and sometimes dont. People will forget about this whole thing eventually. Trust me I know people that had way worse gossip about them and people eventually stopped talking about it. As for your friends, maybe you could tell them that you just didn't want to hurt Lou so you agreed to go out with her, because that sounds like what happened to me. They should believe you. If not, then whatever. It shouldn't affect your friendship just because they think your gay. Just tell them not to spread that around. There is nothing wrong with being gay but I can understand why you wouldn't want people thinking that. Dont stress over the whole thing. Everything will be okay.
