^That sounds like good advice Redrivertears (and a belated welcome back as I see you've recently returned and are helping by using your many years of experience! Thank you!).

**I must add that anyone reading some of the other replies or the OP, try not allow yourself to fall victim to any negative schema or poisoning of your schema (easiest way to explain it is to avoid any poisoning of your expectations...don't expect to have trouble with something just because others are saying they have trouble with it). In my experience, if you are avoiding getting excited then you may very well be falling victim to having read too much negative schema! Luckily the point was driven home to me early on and I realized the truth in it when I saw how some things were difficult that others found easy but especially that other things were easy for me that others mentioned being difficult! (flying was always easy for me and when I saw that some very good lucid dreamers had or have trouble at times, it clicked for me.) I avoid negative schema like the plague (i.e. "nope..didn't see that" or "that's not fact, it's just one person's experience"...or even better resolving it in the lucid dream!).

I have had lucid dreams end while having sex...but I choose to believe that it was not because I was having sex in the LD...my REM was just over (also found ways to stay in dreamland longer even if it seems like the dream is ending...again expectation, or more accurately schema, was key in my opinion). I often have lengthy sexual experiences and I have no doubt that anyone else can too.
