Oh baby, if you lived closer.......
I used to be 100% ler until I got tickled at my first (and only) gathering in 2005. Then, I met my SO and although he's ticklish, he definitely has a ler side (not even knowing about the tickling world). He "ratted" me out one day during some fun when I told him "no" and he told me "you know you love it". I didn't argue back so it's an unconfirmed thing between us.
But, if you lived closer, I'd be happy to show you what being the lee feels like. The first time is the most liberating thing you will ever feel. It won't make you less ler, it'll give you a feeling of completion that simply has to be experienced to be described.
