Well Im younger, only 45... I can tell you that I started getting the urge to let "her" out at least 6 months before I started with NBE...
I was a wreck as far as my physical condition, 40-50 lbs over weight and I was having symptoms of BPH (enlarged prostate).... I was drinking like a fish and eating a terrible diet... I could barely function then, I was in bad shape and needed viagra to do the deed... But It had been 3 years since I broke up with my last GF, I was in a slump getting nowhere fast trying to find another one... Depressed is an understatement....
So Id had enough of that and cleaned up my diet, started doing some LIGHT exercise and cut back a bit on the drinking hoping to feel better and it started working, I was also taking various prostate formulas... Well eventually things got back on track and I was feeling way better than I had in years and my drive had returned in a big way....
Id always been into CD'ing and the porn that goes along with that but Id never really pursued it because I was so out of shape, just a dream for years.... I also had a lot of guilt and shame that went along with that, A LOT....
Well eventually I decided to order some girly stuff online and it was great, REALLY got me going as far as drive goes LOL...
But I was also unhappy because I was FAR far away from being anywhere near pretty
But I kept at my weight loss and diet and as my health improved so did my libido... The better I looked the more I wanted to CD, the more the wardrobe expanded ect...
Well eventually I started shaving my face, because lets face it, a dude in a dress with a beard is pretty funny looking
Id worn a beard for at least 25 years up to this point so that was a big deal...
Id be able to get by with only occasional CD'ing but the desire to get girly was getting stronger and stronger... The shaving more and more frequent....
Also I began really wondering WHY I wanted this??? There was a lot of self examination going on in my head, lots of guilt and shame but also I was feeling much better about myself than I had in years... It was like "coming out" to myself and getting over all of the BS and negative self loathing.... Self acceptance and forgiveness, coming to terms with who I really am and embracing the feminine side, a little self love for a change....
Now for me at least I came to realize what really turns me on is submission to a female and not having to try to "the man"... WOW I tell you that really got me going when I learned to accept that
So eventually I get to the point I want to shave my body... Never did that before and naive me figured just slather on Nair everywhere and shazaam it gone.... All I can say is OUCH, NEVER again!!! Chemical burns all over, it was terrible... But eventually I recovered and Ive been hairless ever since....
So I start dressing girly more and more and getting better and better at it, better clothes, wig and make up ect... So one day I say screw it Im going shopping as a girl because it cant be any more humiliating than browsing the lingerie or make up isle and buying that stuff as a guy....
Those first few shopping trips were pretty uneventful and I realized I was actually getting off on it when the pretty girls would read me but they were very nice regardless... I also realized I didnt really give a damn what anyone thought, I was on a mission....
So I finally have some decent pics of myself and I find a bisexual girl friend online who's also into some VERY kinky stuff, she is DOMINANT, I am submissive....
WOW!!! This is great I can finally be myself with a woman and she actually gets off on as much as I do
So we get into chastity, lots of fun for both of us but actually pretty easy for me because Id gone off the deep end
It was a very hot almost lesbian like deal, she is not really into "normal" man/woman sex and that works for me because Im not either.... In fact I find myself having to pretend Im her doing me to really get off...
She was and is a great help for me putting myself together as far as everything girly goes.... Things get better really fast to the point she was even shocked at the way I was dropping weight and getting girlier and girlier....
Strange thing is Im finally getting in really good shape and my guy is working better than it had in YEARS... But there really is no male drive because I guess I realized that being a manly man does not turn me on and it never really did... It was something I could never quite pull off and it used to really fuck with my self esteem...
Along the way I had been researching everything I can find on TG/TS/TV/CD ect... I found this place and I thought it was interesting but I didnt really think herbs could work.... All the TG stuff I read said you gotta go to therapy and doctors and get on hormones ect...
I start seeing some similarities and can identify with the stories I read of TG girls that go on hormones... I start thinking Id really like to do that myself but Im scared...
So I end up lurking here and learning about NBE... It starts with just drinking my GF's soy milk and taking her menopause pills LOL....
Finally my curiosity got the better of me and I ordered some PM, start taking it and start seeing results
So now Im here and I think I have an addiction to this stuff, the more fem I get, the better I feel....
So wow that was a LONG story I wrote this morning, whats the point here
Well I guess to answer the OP's question for me anyway....
Its not that I WANT to kill my libido, its just that I dont really care too much about it because it never really got me off anyway and I dont miss the "man" at all....
As far as my "female" libido goes, lets just say there are other ways for a man to have an orgasm
