Paul sounds a lot like me....into sports...don't put the effort into planning romance etc etc...he seems to be a very common person...walk out into the city and you can probably find 200 guys in one hour that like sports and want to have sex with you...depending on how long you've known him, maybe you should find out more depth but if he won't open up, that's gonna be hard...
Anthony with you has like 9 things out of 10...in all practicality, you should marry this guy...many married couple lose interest phycally after many years anyways...But one vital part is missing...to you, he is a friend, an activity partner, but not a companion and a person you feel love with...what you have with him sounds like it can last longer than what you have with paul, but it also sounds like you won't be completely fulfilled...
Maybe you need a love square instead of a love triangle...if there were only two men in the world you'd have a problem but there are more...depending on how eager you are to settle down permanently, you could probably find a different guy that you find is more complete (but don't get nit-picky)...if you are near that stage where you feel you want to settle down for a good long time (catholicism and atheist isn't bad for relationship just marriage right? i don't know much about that but/...), then you gotta go with what you feel will be longer...
