Men's chests are beautiful, sensual, welcoming and erotic.
Early welcome comes from the an approaching wholesome nude man's chest. Sometimes called pecs or pectoral muscles dominated by shape, size and often well formed nipples. Flaccid or erect. Always attractive. Sometimes pierced. Waiting to be noticed. Perhaps touched as greeting from a another bud. Always an indicator of what comes next. Usually direct eye condtact and something verbal.
Men's chest are no different from ladies breasts: that is to say they come in all shapes and sizes with no particular type necessarily being more attractive than another.
I've always been lucky to have square shoulders and reasonable pecs throughout my life, not that I spend hours pumping iron in a gym but I do do a lot of sport and exercise. And I think it's fair to say that I have had plenty of compliments about it. No tattoos, completely hairless (naturally) and a piercing in each nipple (generally just a small ring) which I will wear now and again as my mood allows.
