Mookin...you are not going to hell for this.... you are young... hormones are raging.... and there is no shame here or there.... life is not figured out overnight... not by any of us...
like most of us, you have just realized that this is a problem for you... so now you can work on it... and change takes a long time... try to be patient with yourself...
love and accept who you are and work on the behaviors that you want to change....
and no this not change my support for you..
