Yes, it is possible and it happens all the time, to women, not men. The reason for that is human difference that separates male from female, the groin area.
Women riding a bicycle often experience orgasms while pedaling. Almost every time when that happens, they are silence, not making any sounds as they tend to make while having sex in the bed room. This is definitely doe to the fact that it is quite embarrassing if someone notices them having orgasms in the middle of the park while riding a bike.
A described from many women that have experienced orgasm while riding a bicycle, the level of sensation is small, but good enough to put a smile on their faces. The sensation many times starts surprisingly during riding. The triggering of the sensation between the legs can also start if the bike starts hitting small bums on the road. Sexologists always claim that sexual attraction and urges start form the brain. This is confirmed by the same women who had orgasms on the bicycle seat.
The said that the sensation starts when the see a handsome man walking by; when they start to think of sex during riding a bike; and that triggers the sexual nerves in the body and beautiful sensation starts in the groin area. Sensation increases as they pedal up and down with the legs, gently massaging the groin area. It is more likely for women to experience orgasms, if not a great orgasm if their seat is slightly higher. That way the clitoris (female’s sexual satisfaction area) is in good contact with the seat.
Moving up and down with the legs puts more massage on the clitoris, and in couple of moments ‘explosion’.
Most noticeable situations if a women is experiencing an orgasm while riding a bicycle is when she shifts to a slower gears in a terrain that does not require much effort to cross.
With faster pedaling and slower movement of the bicycle it is presumable that she is having an orgasm.
As for males, having and orgasm while riding a bike is very rear, if not doesn’t happen at all. Male reproductive organ doesn’t experience the same sensation as the female organ; the reason is quite obvious- natural evolution. But there is a good possibility that a man can experience an arousal, or erection. The triggering of this situation starts in the same manner as for the women. The difference is that men are unable to experience orgasm while pedaling up and down, because that movement is not enough for the final ‘explosion’.
