I’ll try it out and report back 
I’m doing PE exercises to gain more length, after that i’ll work on girth.
My goal was to get lucid dreams also but I never made it that far. Got too many other things in my personal life. Doing reality checks every 20 mins becomes a fucking hassle.
If you get lucid or into the astral world you can modify your body to look how you would want it to look in the physical world so I guess that’s a pretty desireable skill to have.
One can alter his appearance, like eye color, hair regrowth, penis size, breast size for women, muscle mass, it’s quite sick to be honest.
