I have a similar thing. I am a healthy young man, well, within reason, as I’m rather detached and not a volcano of hormones, but I just don’t get to want to have sex with someone, fantasise about it, that kind of thing - even if I actually do feel attracted, or even stimulated sometimes and yes, have to guard myself from temptations from time to time. Because my mind generally doesn’t give in, I’m beginning to wonder what kind and degree of reaction my “body” (including perhaps emotions) feels - and yeah, at that point, we can talk about something sexual. But when it’s just something that wouldn’t be gay with a person of your sex, or incenstuous with a blood relative, that’s hardly a sexual thing. I suppose we have more to guard ourselves against than merely the sexual coveting, since people cheat by emotional affairs and thus some people probably steal others’ spouses that way, but I have trouble seeing that happening just because someone appreciates someone married’s qualities, finds something attractive with him. Obviously, still got to be careful with those things and still a good idea to talk to your priest about it. Might be a good idea to ask him what to do if such situations happen again in the future.
