Why almost after every intercourse with my girlfriend I have inflamed head of the penis

Could you tell me please why almost after every intercourse with my girlfriend I have inflamed head of the penis, it doesn’t hurt to urinate though, it’s just swollen and I have white discharge. Could it be because of the low-grade spiral, or is it something else? It’s swelling for at least 3 days, but if I wash my penis right after sex then it doesn’t happen. Though, it’s very uncomfortable since I want to enjoy all the nice after-sex cuddling. (Male, 23 y. o.)

During intercourse, different microbes get onto your foreskin which might cause inflammation – formation of increased discharge, redness, swelling, if you don’t wash it right after it. Your girlfriend should see her gynecologist and take care of that. Regular foreskin inflammation stimulates its traumatizing which in its turn can cause formation of adhesions which as a result will narrow foreskin ring – foreskin phimosis will form.

At this moment you should use condom to prevent your girlfriend’s influence on your foreskin.
