If you must, then I would recomend spending time away from it, focus on other things sexually, orchestrate fantasies that do not involve tickling, and work on it until you find something else that turns you on. Truthfully, you will never be rid of it, and I don't know why you would want to. I understand it can be hard in a relationship and especially hard if that relationship is a commited one, if your partner does not share in your desires. Bear in mind that there is nothing wrong with you. I hope you are seeking this remedy for someone very important to you. Otherwise, I would advise you that you are who you are, and your sexuality is a part of that. Anyone who is in love with you should know that and be able to accept it up front. The best overall solution is to find someone who is ok with your sexuality, or someone who shares you unique gift, because in the long run, you will not be able to change it, only repress it, and that is not healthy.
