You will know when it is the right time to go through with your decision. It can be a trigger caused by that person you like and can\'t be with because of your anxiousness about your size.
My advise, though, is to not wait so long that when you do meet that person, you end up passing on what could be a great relation because you hadn\'t acted on your desire sooner.
I wish I had done this much sooner (knowing what I know now), but due to research and study of this course of treatment, I prolonged my decision. I recently met a girl who is quite attracted to me, and I have to wait several weeks before I \"let\" her blow me because I\'ll be in the healing stage. So I have to think up good excuses to defer the ultimate outcome. I think she\'s ok with it though, so I\'m lucky. Some girls will wait, some will move on.
Good luck in whatever you decide, and only you will know when to proceed if that is the next step for you. Personally, I think it\'s worth the risk in my case only.
If it doesn\'t work out, I\'ll be ok with that too.
