Dear everyone,
I am kindly seeking your advice on a penis-related problem of mine. I am a 28-year old male.
For a couple of months I have had weird 'wrinkles' developing on my foreskin and the related areas mentioned in the title. What could it be?
I am not experiencing any physical pain (the only pain being mental), however, I have noticed difficulties in getting an erection as a result. I masturbate probably too many times a day (3-4 times/day on average). I am in a relationship and we do not have sex too often due to distance (thus, no multiple partners or anything). Please advise. Thank you! 
I would also like to add that sexual intercourse (and recently masturbation too) feels substantially sore (i.e I don’t really feel anything).
I don’t have a scientific explanation for what this is. You mentioned that you’re masturbating 3 to 4 times a day. That is excessive. It could have contributed to making your skin look that way. If you use your hands a lot, the skin changes. The same could have happened to your penis.
As for you struggling to get an erection. That could be down to too much masturbation. Especially if you’re watching porn. If you’re masturbating that much and watching porn alot also I advise you to check out a site called NoFap. It is dedicated to overcoming masturbation and erectile dysfunction caused by excessive masturbation and porn use.
I think this is most likely related to your frequent masturbation. As JakeWoods suggests, this will be also related to the amount of exposure you have to any visual Pornography, that is, obviously, if you are actually using it as part of your masturbation practices.
As I have just recommended to another frequent masturbatory on here, you need to start restricting the amount of masturbation you do. So, simply, don’t even try going from one extreme to another - you need to gradually ease yourself away from the typical frequency you currently have. In psychological terms, what you are obtaining from your frequent masturbation is a ‘pay-off’ or simple satisfaction cycle that is feeding on itself. In one sense, it is an addictive process. You need to find some way of breaking this ‘addiction’ and for this you need to creative a different set of satisfactions. So, you could use simple will-power and decide for yourself that you are going to get yourself away from your current regime of practices. You can create alternative ‘pay-offs’, such as regularly doing other stuff that you find equally, or alternatively satisfying - something you can do at home, or where ever it is you most frequently masturbate.
Essentially, initially reward yourself by determining that you will ONLY masturbate once a day. Once this becomes an accepted ‘norm’ for you, and you do not want to stray back to 2, 3 or more times a day - then add in days where you abstain completely from masturbation, again when this becomes the ‘new norm’ add in further days, and so on until you can restrict yourself to masturbating only 3 or 4 times in total a week. As I say - you have to determine for yourself that this is what you want to achieve, then, put in place the alternative rewards you use, that is do other stuff at the times you would have otherwise have been masturbating, or when you feel the urge to do so …
