I finally left my ex 9 months ago after 10 years of no sex and no willingness to resolve the issue on his part. In that time I have used a vibrator periodically. Not especially frequently, but I guess over 10 years it all adds up. So I now find that I can't orgasm by hand...it's like I have desensitised and only the vibrator will do it. However I am also on sertraline (have been for several years.) I know that ssri's can make it harder to orgasm so maybe this is the bigger issue? Any insight would be very much appreciated.
