Don't feel weird about it mate, because I'm exactly the same. (Mind you, I'm as weird as they come! Heh heh.)
I love tickling a girl much more if she's clothed. Nudity saturates our consciousness every moment of the day. Pin-ups in magazines and newspapers, the Adult Channel.... the list goes on. Tickling is a turn on to me and a favourite form of foreplay, but it kinda takes away the tickling aspect if the girl is naked. If she's your girlfriend anyway, you get naked when you have sex, so why need do it with tickling too? Nudity has gotten very boring for me.
Besides which, I seriously love denim. Nothing makes a pair of bare feet look sexier than to see them protruding out of the end of a pair of jeans or khaki slacks. Dunno why, but I just love that look! :tounge: :redface: 😱 I'm definately a jeans & t-shirt man. (And an ENGLISH one at that! 😀)
