I don't have a phobia about being tickled. I can dish it out, I guess I can take it also. However, I do have issues (not necessarily a phobia) about bondage. It absolutely intrigues me to no end to watch someone get tickled in bondage. When I watch videos, I have to remember to blink sometimes.
But, the idea of me being tied up and tickled with no way out nearly scares me to death even though I'm very curious about how it would feel. I don't trust anyone enough to try it out. I have these thoughts about being left there tied up or someone tickling me way past my limits and I wouldn't be able to stop them.
Also, there is a member on this board that loves to be tickled, but does not want tongues to be used. Real saliva aversion.
