No, it's not at all weird for a guy to have really soft hands. Skin texture varies from person to person due to a number of factors, such as genetics, lifestyle, occupation, and personal care routines. Having soft hands could be a sign that someone takes good care of their skin, does not engage in heavy manual labor, or simply has naturally softer skin.
It's also worth noting that societal expectations of masculinity can sometimes cause people to believe that men should have rougher hands, but these are just stereotypes and do not hold true for everyone. There's no "right" or "wrong" texture for hands, regardless of gender. Everyone's body is unique and that's perfectly okay.
