Yes, actually, and I also have a foot fetish in addition to tickling, which can be an awkward thing to share as well. Anytime someone has a "preference" "fetish" or "alternative lifestyle" as tickling and feet can be called, it can be very uncomfortable to share with people.
Your post didnt specifically state whether or not you have a significant other that you are trying to share this with, so I really couldnt tell the point of your post. I havent been into tickling for that long, and I dont have a girlfriend at the moment, but when I did last have a girlfriend, I had my foot fetish. The way I handled the foot fetish with her is that I got to know her for a while, and made the fetish just a part of our overall sexual conduct. It seemed to go over better that way. Sometimes a significant other will be more responsive to their partner's "fetish" or "preference" as it may be if they feel like their needs are being met, and the fetish is just a part of their partner's affection for them. I dont know if this helps, but this is what I find. When I again find a girlfriend, my intent is to get to know her well first, and then after a while, get into the foot worship, and playful tickling, before completely expressing the depths of my tickling fetish, and finding out whether she is receptive to serious tickling, bondage, or such. My philosophy is that if she feels comfortable with me, knows that I care about her feelings, and understands that it is important to me that she is satisfied and happy, she will hopefully be understanding and be more responsive to what I need from her as far as my fetish or preference.
I hope what Iam saying helps you, because this has just been my experience with having a fetish and girls. Take it slow, be understanding, and hopefully, you will end up being rewarded.
