Welcome to HCM.com
from one's palm can be transferred to the genitals. It was an old concept that they cannot be transferred.
Secondly, you might be suffering from 'Molluscum
contagiosum' which is an STD
(though not necessarily transmitted ONLY on sexual contact). However, to make a diagnosis of skin disorders, a close examination is essential.
In my opinion, you need to seek medical care.
Wish you a healthy life.
