I think it's more to do with how a guy confidently works his physical appearance and personality. They all come into play. For example, a guy could be funny, confident with a great personality and be average looking and I would consider him hot. On the other hand a guy who's gorgeous but acts like a total tool wouldn't be considered hot in my opinion.
Their smile, and their personality. If their smile if infectious and they make me laugh or tease me (playfully, and they have to be able to take what they dish out), then the person instantly becomes hotter to me
What makes a guy hot for me is a guy being an eligible bachelor, you look poor and high end girl like me would never take interest in you ...Features 6'2 inches fit but not skinny ... Wavy light /brown hair ,blues eye :)
to me a guy who has a is nice to me and makes me feel special if he does that that then he is really hot to me but some of my friends just like guys who have abs, and nice eyes and stuff and would like and date any guy even if he was a jerk
i think it's mainly determined on how his body is like(toned, fit etc) and on how attractive he is facewise.
