sex in a shower not my wife

sex dreams are just that
sex dreams, not much to them, guys have them all the time
this one though was different
it had a lot of other symbolic and emotional things in it :

I was at work (i work as a lifeguard at an indoor pool) and I can't remember what lead up to it but an extremely beautiful woman approached me. She was beyond my definition of beautiful.
She was tall. I am 5'11" and she was at least 7 inches taller than me.
she was perfectly shaped all over, almost golden skin. Not white, or tan or brown...some color I can't really describe. She had the most beautiful face I'd ever seen. Better than any super model.
We went to the shower, both naked and began making out and having sex. She had her arms wrapped around me with such loving embrace. I felt so overwhelmed. My whole being felt so good. She could see the top of my head and noticed my hair was thinning. I felt embarrassed and she smiled with bright eyes and said I looked good. The sex was so incredible feeling. We walked out of the shower and I remember heading outside and then at that moment thinking about my wife.
Inside I felt I needed to tell her I wanted to be with this woman and I was going to say something to the woman and my teeth were loose...just like dentures. they were exactly like dentures coming off in a group both top and bottom teeth and I could feel them in my mouth and I kept trying to fit them back onto my gums by pushing them up with my tongue.

the dream pretty much ended there
I tried looking up symbolism, and I got some ideas, but nothing really worthwhile.
this dream was so vivid, visually and felt so good, but it just confused me at how it ended.
anyone got any thoughts on this?

loose and falling teeth is a very common dream for many people.

I don't know how old you are but there are two elements in that dream (teeth falling appart and hair thining on top of the head) that I think hint to an anxiety concerning growing old.
Maybe you long for a new start (and thus wish to say your wife that you need to leave her, to be with someone else - the embodiment of beauty and youth actually) but you feel your body growing old despite that.

Does it make sense?
