A pretty sweet first LD then! I'm particularly impressed by the feeling of warm sand on your feet... I can't remember having such a specific and intense feeling in any of my LDs. Reading that reminded me of my first LD. You'll learn to fly eventually.

You mentioned two things: Learning to fly, and making love. In my first LD, I tried the first but gravity caught me, it was as if I was doing a moon jump but with a hard fall. I just reminded myself that this was a dream and that I could do anything - and on my third attempt, I flew! It was one of the greatest feats of my lifetime . After flying around and enjoying omnipotence, I decided to try the latter, and I summoned a girl. Well, it was actually an angel, and she was flying faster than me. But I caught up with her and stretched my arm out, but then I suppose I got nervous and woke up.

Sex is famously tricky for some LDers, so try some more basic stuff first.

Cool dream though, well done.
