well my boyfriend has been complaining of itchy palms and when i looked closely they were sweaty, had tiny little bumps all over the pads of his finger tips and half way down them. plus the pads of his fingers sometimes peel too, anybody know what could this be and whats causing it? or if its due to a sexually transmitted disease?

i dont feel hes cheating on me but id like to know why his hands itch so badly sometimes
