As for the libido and performance anxiety goes. Well. (im a 21/male).
Libido is a fairly big issue for me. I never really get turned on,
hormones racing, etc. The only time i get aroused is at random times
when alone/lying in bed or just random non sexual moments. etc. However, in saying that if a girl was to take off all of her clothes and stand butt naked infront of me and ask for me to give it to her. i would have no interest what so ever nor be interested/bothered or turned on by it ?! (i am 100% straight btw)

The anxiety side seems to have decreased a great deal to the point where
i am relaxed in nearly every situation (before used to be able to feel
the anxiety rushing through body, shake a bit, etc etc natural anxiety
reactions. However. i always managed to get the wild man to stand tall in the end and carry out the deed). So now it is opposite. I feel i COULD indeed do whatever was presented to me at the table. However the problem is now my Libido/arousal levels are so low that i wouldn't be able to be aroused by any of it nor be able to carry anything out...

In saying this 'if' i have been in a committed relationship for a while...
then there are no issues what so ever with libido or performance anxiety, i can basically make it go up or down whenever i want and generally im the one asking my partner for it on a regular basis :S

Being single and Basically even with the people ive 'already been with' so to speak, on numerous occasions. I still have issues in geing aroused/turned on despite being relaxed and capable of performing IF i was indeed aroused to begin with..

I hope this makes sense to you as well, it is quite confusing for me as i do not understand why my libido is so low. It shouldn't be anxiety related because i used to feel nervous and what not when about to carry out the deed and would basically lose the hard on due to this anxiety.. I do not even want it anymore nor get turned on by anything anymore. So i basically dont even get my foot in the door like i used to.

Not sure as to what the problem is, not sure if you guys know what it may or may not be caused by. Maybe someone has or has been through the exact same thing.

All i know is that it sucks... I do in heart want it. I do in heart crave it from time to time. But when push comes to shove and the opportunity arises i'm simply not interested...

cheers in advance.

P.S i will also add that it never used to be like this.. This has only occurred in the past 6-12 months or so. before that since maybe age 15 until recently my libido levels i would of considered were normal.
