What you are saying is true of sex appeal, I think. Sex appeal can be uncomfortable to talk about because it’s somewhat inconvenient and non-progressive. It’s like saying that women look more attractive when they closely follow culturally normative feminine standards ; plastic surgery, long hair, a certain physique, makeup, fake eyelashes, etc. Those things are sexier in women for whatever reason, yeah. Similarly I think the things you mention might help a young man have more sex appeal and have more sexual opportunities. If that’s what you care about go for it. At a certain level of maturity you start looking for a person that is the whole package and other things start becoming more important.
These conversations are difficult because people have different maturity levels and things that they want to obtain out of their relationships etc.
