I am a naturist, and some women in our community claim that a “real” naturist man would not get an erection without being sexually aroused. I believe spontaneous erections happen without sexual arousal. I remember multiple daily erections during my elementary and middle school years. What in the world causes an erection in math class? Aren’t spontaneous erections the sign of a happy, healthy male of any age rather than a sign of sexual arousal?
An erection is a complex physiological process involving the brain, nervous system, hormones, and muscles. It makes sense why women who are naturists might associate erections with a desire for sex; many of them may have only had experience with an erect penis in a sexual context.
