The thing is Phil has had more relationships with Women than he has men and none of the ones he's had with men were reciprocal in what he wanted from it.
What protects OPL is he's not able to conceptualise a relationship in real terms, Phil comes across to the kind of women he is interested in as a smart mother fucker (they are normally young or slightly more exceptional than himself) once they are in a relationship with him the soon realise that Phil isn't even close to being what he claims or looks like, and that causes a fair bit of drama.
Having wrote this really makes me want to finish my Phil and Sex write up but I can't write more than a paragraph or two at a time before having to take a break and a few stiff drinks. Understanding Phil and his sexuality and his relationship with sex is hard hell it could cause a terminal case of autism by osmosis, and trying to describe it is hard really hard, there are a number of concepts that most people can't understand that Phil thinks like, the best example of this is trying to play Pictionary, Jenga, and Monopoly fused into one game and it's the first time you've seen it and your very very drunk... that's what getting into Phil's head feels like at the best of times let alone when he feel's horny, and I've had to do it many times and I wouldn't wish that on anybody.
