Suggest Treatment For Erection Trouble After Excessive Masturbation

Please help! I m 29 yo and have been masturbating frequently as long as I remember, on average at least once a day sometimes less/more. I am without a doubt an excessive masturbator. The problem is now I ve noticed over the past month or so it has been very difficult to achieve an erection. I ve had weak/soft erections on a regular basis. This comes at a bad time as I am now in my first serious relationship, and had sex for the first time recently and the first time I wasn t able to maintain an erection to penetrate and the second time I was but left little pleasure for me. Now that I m in a relationship that will hopefully have sexual activity, I m finding it a possibility that I ll be unable to perform and I think the stress/depression is making it worse.. I can t have a solid erection during sexual activity or masturbation. Only occasionally in the morning waking up will I have a decent erection, and even then it seems softer/weaker than past. I haven t had a rock hard erection in months. The concern brought me to the internet to search on the effects of over-masturbation and to add to my fears I found pages of sites which said erectile dysfunction and impotenence, as well as weak/soft erections are a definitive consequence of overmasturbation as it effects chemicals in the body. I m scared to death now that after 29 years I m finally having sex and won t be able to enjoy it, or even perform at all. Is this permanent? If I stop masturbation, which I m pretty sure I m capable of doing, for a period of time and then lessen masturbation in the future.. will the chemicals balance themselves out again and I can achieve a firm erection? or is this permanent damage that has been done that will require some kind of drugs? I m 29, and have been masturbating for about 13 years. I thank you in advance for your time!
