As was said in an earlier post, there is the possible option of Viagra. (Pre-transition I preferred Cialis as the effect lasted much longer and the headaches were a lot more bearable.)
I intend to discuss this with my Dr next time I see him as permanent loss of ability to obtain an erection is something I want to be absolutely sure of before I commit to SRS.
My G/F (MtF) thinks she might want to experience penetrative intercourse with a bio-strapon, and I am okay with doing this to please her a few times also before I get rid of it. I'll just grit my teeth and think of Australia I guess.
