I once read a long time ago, in the 80s or 90s, an interesting book: "Notes of a sexologist", a type of scientific-popular. Who does not remember the author, unfortunately, he presented cases from practice.

I remembered an interesting case.

The woman turned, complained that she regularly gets an orgasm on her bicycle when she makes her trips. This bothered her, because disorientation occurs during orgasm, which is ultimately dangerous during movement.

It was examined by gynecologists and other specialists, no pathologies were detected.

This sexologist began to penetrate: what a bicycle is there, maybe the clitoris rubs around the seat, etc.? to

I started experimenting on a bicycle trainer – no orgasm! In no situation.

I started to find out further: it turned out, an orgasm always occurs in a certain place of the road. She pointed to this place and the sexologist examined it: it was a descent, that is, a woman was passing it at high speed. On the sides of the road grew evenly near high topoles.

Also, the woman pointed out that the orgasm occurred mostly in sunny weather.

After comparing everything, the sexologist came to the conclusion that when a woman is driving down the slope, the sun and shadows of the topols create a flashing light for her, like the stroboscope effect.

And that light causes an orgasm.

After reading the literature, the sexologist found the appropriate pathology for this phenomenon: it must have been a tumor of the pituitary gland (a gland located in the brain).

With further investigation, his guess was confirmed.
