I have been masturbating from over 10 years easily. Nearly 4-5 times a day. Sometimes more or less. Now when I have sex with any girl (when I do without condom), they have extreme vaginal pain, inflammation and problem in peeing. I feel no pain or discomfort. But exactly same symptoms happen with every girl. I have had swollen penis (the area just below to top dome) 2-3 times in lifetime. Scared me that time, but it went away in 2-3 days.
I am scared if I have
STD, but very concerned of what could it be.
