Dreaming of losing my teeth — very unwelcome I'm a-Freud

I had an odd dream last night: all my teeth started falling out one by one. A girl at work said it was a sex dream, a dream expressing the fear that you are no longer sexually attractive. Perhaps. I must admit that I haven't consciously considered whether or not I am still sexually attractive. We're all a little vain, but I don't think about myself and my looks very often at all.
I do know that at my age jumping into bed with a woman without just a little time - a little flirting time - would be something close to a disaster. I haven't had sex in almost ten years, and although I know quite a few of the tunes, I would need a little time to tune up.
The other trouble is that, for example, the women I fancy at work are all at least 20 years younger than me, and not in a million years would they consider me as a potential sexual partner. There is one writer, a raddled old piece who most certainly looks older than she is because she looks about 90 but cannot yet be 90, who for a few days kept making cow eyes at me when she first joined, but that rapidly ended when she realised that in her I simply was not interested. I shan't give you her name, but she spent, or better, misspent a large number of years in the 70s and 80s as a showbiz correspondent out in California and looks as though she crammed about 100 years worth of partying into 20 years. She has not aged well.
Anyway, as I was saying the sweeties I am interested in (and I am sure it has never occurred to them that I might be) wouldn't look at me in a million years. Hence, I should imagine, my dream about losing my teeth.
