Be very leery of any claims about enhancing growth like pumps. There's almost no substance to any of those claims and they can often be harmful to the full functionality of your genitals. Some moderate pumping just for temporary fullness is probably fine. This goes for cis guys as well, many of whom have insecurities about penis size and try those things.
I recommend a documentary on Netflix called
Unhung Hero.
Take heart in knowing that it's a non-issue or very low on the list of priorities for many people. Maybe I'm a weird gay man. I'm not much into dicks at all. They look very ungraceful, all saggy and wrinkled. They make a lot of your life ungraceful (squished when sitting unless you sit with legs way apart,
scrotums sticking to thighs while walking, etc.) I think smaller is just more attractive, certainly visually it is. I just need it to work. The fact is that a large penis, a small penis, and a clitoris all have the same number of nerve endings (closer together or spread further apart) and that's what matters, i.e. same amount of pleasure from stimulation. Some characters in a book I'm writing have internalized testicles and a retractable penis. I think that would actually be ideal. It seems pretty odd to me that we would evolve to have these always external (and therefore always vulnerable) genitals. Many animals have evolved differently.
But I digress. Sorry.
