I am a 25 year old sexually inactive male.
I used to masturbate regularly till 2007 and then stopped for a good 1.5 years.
Post that I restarted masturbating about a year back (once in a while), I stated noticing light yellow/white discharge happening practically every other day.
A few months earlier, I noticed a deep red swelling on my penis when i pulled my uncircumcised penis about 1/2 a cm beneath the glans. it is about 7-8mm in diameter and practically of the same colour as my blood.
That is when i felt that maybe my discharge was some sort of a pus coming out of this rather than penis mouth.
About 3 weeks ago I was watching some stimulating material and had an erection, when I went to the bathroom to clean up the precum, I saw slight amount of blood mixed with the precum.
I have so far not experienced any pain or discomfort, and had i not pulled back my foreskin to such level, I probably would not even have discovered this.
I have not been to a doctor still regarding this. Please suggest what could this be and what should I do about it
