Why do I get erection while horse riding?

[TheAli]

Now erection is something you commonly refer to a sexual stimulus. It's also weird for me but whenever I do horse riding (It's one of my favorite sports, I love it) I get erection. But it's always non sexual I mean how can it be sexual? Though I do have in mind about something under control. Is it kinda submission feeling? I searched on Google nd answers. com but no one else has it. What is it? Do you have it? Plus I'm completely normal straight 19 year old guy who is not desperate either I've had a lot of girls. What do you think about it?

Well it could be that the moment of the horse is causing your body to act strange.

[TheAli]

Yeah it's a pretty strange reaction because it happens every time.

It is because you are 18. That is why.

[TheAli]

I'm not the only 18 years old in world.

[MangoB83]

Yes but erections happen all the time at that age.
