Hi Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
According to your symptoms you should be suffering from
balanitis. It is common in non-circumcised males. It is caused by collection of
smegma in between the foreskin of penis &
glans penis. You could wash penis carefully with warm water by pulling the foreskin back.
Other reason might be a Sexually transmitted infection like
genital herpes. Genital herpes lesions resemble small
pimples or blisters that eventually crust over and finally scab like a small cut. These lesions often appear within the first two weeks the virus is transmitted and can take between two to four weeks to heal.
so until you figure out what you have, you may want to be extra careful about protecting your partner from direct contact with the lesions or from genital to genital contact.
If problem persists, visit a physician and he would provide you with a specific diagnosis.
Hope your query is solved
Get well soon
