That's great, Antonios.
Achieving lucid dreams for the first time is one of the best feelings a person can have. It can certainly repeat itself in new and different scenarios. When I am having one of those "trapped" dreams and realize that I am dreaming, the resulting feeling of freedom is overwhelmingly good.
As for sex in lucid dreams, I have an anecdote that I find pretty amusing. I sometimes think my dreams are designed by someone who is a combination of Woody Allen and Franz Kafka.
I was having a dream about being at an airport. Now, whenever I am at an airport I like to do some people watching. I find, for some reason, there is a remarkably large number of very attractive, and sometimes exotic women at airports. I like watching them and wondering about their lives, where they come from, where they are going to, etc. Well, in my dream I realized I was dreaming as I watched this very attractive blonde walking by. Bluntly, I said to her, "You! Have sex with me!" She looked at me for a moment and then said, a-matter-of-factly, "No." "What?" I said, "This is my dream!" In the same tone she said, "I know it is your dream, but I am still not going to have sex with you."
I was very surprised and amused by this. I had to laugh. What a spunky woman. I guess I was lucid but didn't have "full control."
But, as for sex in dreams, I find that barring any subconscious reservations against it, you can have sexual dreams simply by desiring them very strongly and imagining your dreaming taking sexual turns at various times during the day.
