There are legal ways to get a hold of the hormones as well but its not easy and specifically not safe unless you really understand medical journals inside and out and follow how they've progressed over the last 30 years. Also in terms of CDing in public just go in logical progression of transition before u make any permanent leaps and comfort wise just feel your way around. If you do it with a person who knows they're way around you'll have a lot more fun faster
