question: Hello doctor, I am a 34-year-old male in good general health. Until 20 years of age, I never experienced any issue with erections or sexual health. When I turned 20, I had an episode with my girlfriend where over two consecutive nights, we had no sex, but rather very prolonged foreplay. Due to the prolonged arousal, my erection stayed for most of the night, without ejaculation. This episode of two prolonged erections and arousal obviously hurt my penis as it went through some visible changes back then, both in shape and feeling. While it was not painful, it lost some thickness and the side erectile tissue eventually lost some elasticity, becoming somewhat hardened in a flaccid state. Since a slight curvature initially appeared, I can only guess this was Peyronie’s. Eventually, in the course of some years, it did recover partially and as of now, there is practically no curvature at all. However, the erectile tissue is still not as it used to be, somewhat hardened and when I have an erection, the blood seems to get trapped in a way in both sides of the penis, while the glans have difficulties getting sufficient blood and arousal and often remains softer. I have no problems getting and maintaining an erection myself, but when being with a partner, it tends to be more difficult and the erection often goes away quickly if not actively stimulated. The softer glans often leads to less control and premature ejaculation. I assume I may have gotten some degree of penile fibrosis, which was triggered by the episode of prolonged erection when I was 20. My question is, would there be a (natural) way to help reduce this tissue hardening and enhance regular blood flow, particularly to the glans. Since this is not a serious issue and it seems the damage was not that substantial (I still have morning erections for example, and the feeling is often close to normal), I would be looking to some natural therapy with as little side effects as possible. I read about some allegedly very good results of combining L-arginine and pine bark extract when it comes to enhancing erection quality overall. Would you happen to know about this or could you recommend some other natural treatment options, which would not cause any other health issues? My main concern would be getting priapism due to some medicine like Viagra, as it was exactly the prolonged erection that caused my problems. If Arginine and pine bark extract are overall safe, I would be glad to opt for this.
