It has been happening since Jan 12. Also, when I went swimming on the 21st, it kept sticking out & I have been told this is to do with wet dreams. Think it happened last night as well. Been to two doctors with the first saying it is to do with change & second saying it could be the skin building up to it or puberty. I turn 21 in August, so could it be delayed puberty. Also when I go to the bathroom, sometimes it feels tight or there is a tightened feeling when going to the toilet. This occurred randomly as well, as I did not have this feeling before in my life. People have said it could be puberty as well. However, I have yet to be properly disclosed on the issue. Been told this is normal as well & nothing to worry about. I have also began to feel less of it as well, mostly the front nowadays, in comparison to when it started. If anyone could please put my worries to rest, it would be deeply appreciated. There is no blood as well & I also feel it on the left side when sleeping on the left & sleeping straight is my only option. Also have to put my legs apart as well, but this could be due to puberty & growth?Also feel it on the left side & this is maybe it brushing against the side when sitting with one of my legs on the other, crossed to be more precise.
