How about story and/or quest line, where Todd starts down full gay path, NO gay content between MC and Todd of course...
where he helps you hook up with women by Todd taking the woman's boyfriends/husbands,
and you help him pick up men, by stealing the mens girlfriends/wives.
Would make a good wingman in this case. A gay friend, where you help each other with hook ups.
That way you wouldn't need to share, no voyeuristic/watching, no ntr, no .etc.
