Tip of my penis is red. It happens after masturbation or sex.

Customer Question

Tip of my penis is red. It happens after masturbation or sex. I was treated for chlymadia and the redness went away and came back after I was off the antibiotics. Also, recently underwent surgery to remove a cyst on backside and during that time I was on cephalxen and the symptoms in my penis went away but came back as soon as I was off the antibiotics.   I tested negative for chlymdaida and gonorreah. So, when I masturbate or have sex my penis tip gets red and the top of my penis is red and it wont go away. What should i do?

Usually the tip of penis getting just red, or in medical terminology it is called erythematous, is usually due to engorgement and "blockage" of the valves to open completely to release so blood flows back. Also, another problems is that you might be having a histamine release cause this redness due to irritation of the penis. You can try something simple at first using an antihistamine, a non-sedating one such as claritin or zyrtec and see how that works, and you can take these pills once a day (especially if you are "active") and see if this works. If you tested negative for the STD's as mentioned in your question, then you should be fine. Take care.

Its not just the tip of my penis. The redness extends a on the top of the head also. Everything else looks fine. Will the antihistamine help with all that redness. Also, there is some slight discomfort but not during urination.

Yes, that is exactly what I'm talking about. It should be fine with the antihistamine - but realize it doesn't work immediately so take once a day.
