Penile tattooing can prolong erections. The reason may be due to the henna, ink or other natural pigments used to make the tattoo. Penile tattooing itself requires great precision, due to the hypersensitivity in the given area. Even a little carelessness with the needle during the procedure can cause blood vessels to burst, causing blood to flow outside the vessel wall. The effect is a constant influx of blood into the penis, which may also be the reason for the longer erection. Specialists advise in the case of such signs to consult a medical professional immediately to avoid subsequent problems that may lead to erectile dysfunction. The risk of infections after the placement of the tattoo is significantly greater in such cases, experts remind. The most serious are life-threatening infections, such as HIV or hepatitis C, which are caused by unclean needles. Iranian urologists report a similar case in a man who tattooed his girlfriend’s name on his male dignity. A few days after the tattoo was done and the post-procedure pain subsided, the man noticed that his erection lasted much longer even after ejaculation. He refuses to consult a specialist doctor, based on the fact that he is in good physical and sexual health.
