15 years ago I had a girlfriend (we were 16-17) and one day she said she really liked one guy and she in case they had mutual sympathy - wants to be, so to say, "in all arms." She asked me to teach her to kiss. A very strange request, because then I was not interested in anything but football in the yard with the boys and I was obviously not a professional in kissing). But naturally I agreed, and after a number of “kissing sessions” she admitted that this guy was me.
