Women love to ride. Its true, and if the small amount of research that has been done on the matter is also true, than suddenly guys have good reason to be a little jealous
Pretty encouraging for all (wo)mankind.
...a sex researcher had a group of women (some of who suffered from something called delayed orgasm) ride a stationary bike for 20 minutes, after which they masturbated. After stimulating sympathetic outflow by riding the bike, the non-disordered were able to stimulate themselves to several orgasms each and most of the women with orgasm disorder were able to stimulate themselves to at least one orgasm.
She treats many women with orgasm disorder using the stationary bike and she has had pretty good and long-lasting results.
Now for a more technical example, we present the most popular scene in "Mädchen, Mädchen"
And finally this less descriptive movie proving that filmmakers can enjoy bikes too. OH FUCK THIS LINK!
Lets get ourselves embedded!
