Help a Girl Out - Penis Related Question

Hello. I'm 21 year old female and I have been sexually active for about 3 years now. Before my present boyfriend, I have slept with two other guys. The thing is that I have noticed that my boyfriend’s penis isn’t so straight. It is band a bit to the right and has some curves also. I have never seen anything like this.
The sex is pretty normal and even good but it looks kind of weird. A friend of mine told me that it is often connected with masturbating. Please tell me is this normal?
Like I said, I have already been sleeping with two other guys and I have never notices this thing with anyone of them.

I know some facts about this because my husband has also the same problems. First I want to tell you that your friend was wrong. This doesn’t have to do anything with masturbation.
In facts, this is one disease called Peyronie's disease, but you shouldn’t be afraid- it isn’t any sexually transmitted disease or anything similar. It is the simple irregular bend in the penis.
It is caused by a buildup of scar tissue in the erectile tissue of the penis, which causes a sharp bend in the penis during erection, because the scar tissue isn’t elastic as normal erectile tissue.
The right cause is unknown but there are some theories that claim that is has something to do with trauma, perhaps during sexual intercourse or masturbating

my b/f penis is not straight either especially when it is erect it goes to the left and near the bottom it bends nothing is wrong with it its just that wat no need to worry as long as it is good
