This is a very serious question and I hope I dont offend anyone, but I
could really use some advice.

I have used meth alot for about 2-3 years and daily starting about 9
weeks ago......and it made myself and gf (nonaddict) sex lives with
each other...amazing. Meth overtook my life (OMG!, say it aint so
lol), I quit with the help of an inpatient program, sober 17 days now
but sex isnt the same. Before me and her would have these marathon
sessions (of course while I missed work, skipped family functions,
etc)....but now sex doesnt really mean awhole lot to me anymore (unless
I start glorifying meth which is dangerous to my recovery). I still
love her, find her highly attracting, very desirable, but I have a hard
time showing interest.

We have been together 4 years, she is my gf and best friend, but now
that my dis-interest in sex is here, she feels unwanted/undesirable,
when in fact, she means the world to me. Our sex/love making life was
great before I got her tangled in my drug web.

Are there any other tweakers in recovery that have gone through this?

Thanks.
