>>18525620its common. i had this occur in high school with my crush. first time we met outside school, went with some friends to the park. we ended up alone and were walking to a hidden “spot” in the deep part of the park. i guess my body took that as reason to prepare for sex, because i got a massive, headache inducing, pulsating erection while walking.
then we sat down and i felt my lower abs tensing up like it does before you cum.
was able to hold back until she had to call someone, i ran off deeper to the woods and got my load out before she came back. funny enough she told me i “acted different” afterwards
