I'm 18, in a relationship for 2 years but still a virgin due to my Premature Ejaculation. Started No PMO at late November in order to overcome my PE problem and today I'm on day 192. My objective was to wait until day 200 and then try having sex with my GF. I told her about my problem and she seems to understand. I still believe that I can't hold my orgasm more than a minute, so I just wanna ask if it could be a good idea to use Xylocaine spray on my penis while having sex in order to become less sensitive! Any suggestions would be nice. Thanks in advance.
