Plenty of people have sex with their hand, or an object. Dogs hump legs. Sexual attraction and the desire to orgasm are distinct.
Sexually attractive? Well yes, if you're humping it you find it sexually attractive.
Psychologically attractive? Only if you have some kind of complex against being labeled 'homosexual' or 'bisexual' while still engaging in coutius with other people of the same sex.
Emotionally/Intellectually attractive? Well, personally I don't find myself sexually attracted to people (and in effect, things) whom I can't satisfactorily engage with on an intellectual and emotional level. I know some people are different and will fuck anything that moves. I've had people tell me so themselves. But I don't think the "Men Who Have Sex With Men" label discusses intellectual stimulation as a stipulation.
