I think you mean change your sex.
Changing your gender, if you were cisgendered before, will just end up making you gender dysphoric, which is no fun, and if you were gender dysphoric (on the transgender spectrum, normally a transsexual), it would just make you cisgendered.
Me, I'm happy with being female.
No gender change for me. Already messed up enough as I am. I think if my gender was changed... it wouldn't end well.
