Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, possibility of sexually transmitted infection (STI) is more.
Rashes on
scrotum, anal itching, raised white cells on blood reports etc are favouring STI more.
Possibility of bacterial infection is more.
So better to
consult dermatologist and get done clinical examination of rashes.
You will need antibiotics and other supportive drugs.
Avoid moisture and perspiration in private parts. Keep proper hygiene of private parts.
Wash your private parts with warm water and
betadine solution 4-5 times a day.
Don't worry, you will be alright with all these.
Avoid
unprotected Intercourse in future.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
