Sex drive and Percocet

[Methuselah]

Swim has no friends or acquaintances who are knowledgeable about recreational drug use. So Swim has turned to this forum for info on this very personal topic. Swim has been using 30 to 40mg of Percoset a day for the past 2 years. Swim's partner has started complaining about Swim's lack of interest in sex. It isn't a matter of physical function but total lack of desire on Swim's part. Is this lack of desire a sort of chemical castration brought about by the drug? Or is it a psychological problem unrelated to Percs? Please give me your opinion based on your own experience. This is bothering Swim a lot and may cost Swim a good relationship.
