Is it bad for men to be more on the feminine side or for men to like feminine things?
Men's expression of aesthetic beauty in Leo and Libra is wedded to power, art, command, communication and rulership. Exhibiting beauty without utilizing power is just being like an ornament with little substance, like Tiktok boys or puppets in boybands are. That's okay for a certain stage of existence but they are not necessarily generating anything as men. Much of this deals with Azazel in symbolism.
Kings, aristocrats and musicians exhibit beauty (some would call this peacocking) as an extension of their power and maybe as a form of visual manifestation. Yes, this can attract women as a huge bonus, but it's never the only reason. Some men who are beautiful playboys or loverboys accentuate beauty to have specific power over women or whoever else they want to be with, which is fair enough, but this is not serious power and can obviously backfire.
Other men choose athletics, fighting or sports (fire signs) to exhibit beauty which is manifested in their body or the networks of their peers (fire for air).
You don't have to be
physically beautiful or artistic to be beautiful in the masculine sense, this is not for every man either. Individualism and war (Aries, Libra is the sign of the adversary too), so can violence (used properly), eloquence and mediation can make men beautiful (all Aries/Libra concerns), so does wisdom, along with humor, fair judgement and advancement (Sagittarius) as in the case of Socrates, so can philanthropy, advocating for the masses and genius (Aquarius). Communication, being a near presence and using the mind (Gemini) can as well.
Leadership, wealth, showing off and passion (Leo) also work.
Being good 'in' the feminine realms can bring this beauty out but these areas will always be more challenging and are designed to be difficult realms for men. Being a 'motherly' man is almost oxymoronic so there are other areas of Cancer that men invest into. Thanks to Saturn, Capricorn is an 'easier' sign for men to key into (just as Libra is for women) but its nature is still fundamentally feminine: success and gravity are always slipping through men's fingers on a knife edge whereas they are more familiar subjects for women in daily life.
Likewise many women adopt a Libran alter-ego every day clad in heels to go to work, communicate with everyone and be the mediator because Venus lends itself to the concerns of women well, but this is very hard for many. It's still a masculine sign.
