Does Masturbation Cause Small Lump/dot On The Penis Head ?
Thanks for the query.
After reading your description, primarily I feel that this might be a non concerning problem and you might not be suffering from any serious condition.
Now let me discuss all the possibilities, that are present at your age of 21. Following are the possibilities--
1- It could be inflamed and enlarged sweat gland.
2- It could be inflamed sebaceous gland.
3- Any micro abscess.
At your age these are common possibilities.
What you will have to do now are:
1- Maintain proper hygiene.
2- You may use topical antibiotic skin cream which are available the counter for 7-10 days.
3. If the condition persists or the size increases then consult a dermatologist.
Please don't be embarrassed of this condition, it is a very common and benign entity.
Hope this answers your query. In case of any doubts, I am available for the follow ups.
Regards.
