having a curved penis is perfectly normal. more men than you thing have a curved penises.
curved penis runs in the family and i think this maybe the case with you. i would strongly suggest that you speak to you father or brother to find out if theirs is the same. more than likely it is and they too may be concerned about it too, not realising that is it normal. please dont be shy, you are grown men and yous can discuss how yous can deal with it.
it can also be Peyronie disease, this is usualy cause by scar tissues but is not always the reason. i dont thin you have this cause Peyronie’s can causd disconfort during sex and some pain when erect. im sure if who have problems when erect or having sex, then you would mention it in this post.
if you think you have Peyronie’s then please visit a doctor. i think there is an operation to fix this.
