The following really are true experiences.
My first "normal" sexual experience with a girl was when I was very young. Visiting friends of my parents I was put to bed with their, slightly older than me, daughter, (Oh! the innocence of parents!) because we were tired but my folks didn't want to leave yet. She wanted to do the usual "show me yours and I'll show you mine" - I reluctantly agreed but didn't really want to play. My first ever sexual experience had been some time earlier when I invented a tickling game with Hugh, a male friend, where the area available for tickling was limited to the area covered by our shorts. As I'd enjoyed being tickled/groped by Hugh, I can only put my reluctance to play the game with Maureen down to fear of discovery as the "tickling" game had been interrrupted by my mother!
When a lad, on holiday with my parents, I was by myself in a cartoon theatre when the man beside me started stroking my thigh. This felt rather nice and I didn't object. He then moved his hand up and started gently squeezing and stroking my "private" bits. As I had been told never to let anyone touch me there I asked him, politely, to stop; even though it felt nice; after a few attempts to persuade me to let him carry on, he stopped and moved away. With twenty-twenty hindsight I'm sorry that I stopped him and wonder if he would have asked me to return the favour and what I'd have got into ... his flies probably!
After another couple of years, I had moved up to a boys only grammar ***** (I'm English BTW so UK readers will know what age I'm talking about and had discovered masturbation while looking at pictures of girls in swimming costumes. One afternoon I was in the home of a friend and we were talking about the Boy Scouts which Brian had joined and I was thinking about joining. I had bought a second-hand copy of "Scouting for Boys" and was telling Brian about a way of rescuing an injured person from a smoke filled building.
The idea was to crouch over the injured party and drag them out on their back. I didn't think I was explaining it very well and offered to show him what I meant. There was nobody else in the apartment. I got Brian to lie down on his back and I knelt down astride him with my knees near his hips. The idea was that he would lock his hands together behind my neck and that I would crawl forward on my hands and knees while he held on tight so that I would slowly drag him along, The idea was that his legs were injured. This worked remarkably well but it did bring his body very close to mine and there was a fair amout of contact between us. I found this somewhat stimulating.
I carried on the demonstration until I got into his bedroom and got his injured body onto his bed. If someone has been in a smoky atmosphere then of course it is desirable to loosen their clothing to help them breathe. Thus, I unbuttoned his shirt and then carried on by unfastening his trousers and easing them and his y-fronts down his thighs. I seemed perfectly natural to then stroke and play with the delights that I had exposed. I could not get him aroused but after a while he asked me if I would show him what I would do if he was a girl!
I'd not a lot of actual experience but had a good theoretical idea from the movies and an inventive imagination! Thus, I kissed him and played with and kissed his nipples. I was kneeling beside his bed but made no move to join him or even to get him to do anything to me. I'd a theoretical idea of male /female sex but nobody had told me of the thngs that male could do to male! Looking back I'm surprised that I didn't ask him to do something about the erection I developed or take myself in hand and show him what I could do.
It was many years after, that I found out about such things as bi/homosexuality and the fact that most people put themselves into clearly labelled categories. I still think that most of us are "sexual" and that different things and people appeal in different degrees and at different times. I still keep an open mind and grab whatever opportunities are offered without bothering about the gender of the one making the offer.
