I had a friend in high school that had this same problem. I know that he talked to his doctor about it and they prescribed him something. I would call him and ask, but he joined the navy and we have lost touch. You are not the only one who has had this problem.

Do you also get hard when this happens?

I'd reccomend may you wear like a menstrual pad in your underwear if you're embarrassed about the leakage. That way, it doesn't show.

Hmmmmm. I don't personally have experiences with ejaculating while doing leg raises. But I do get boners for no good reason. I found that taking deep breathes and thinking of nature imagery/landscapes helps calm me down. Maybe it'll work for u, I dunno

I'm scared, today i was using an ab roller, and i was doing about 100. Near 95 i came all over my self and my friends floor what should i do?

Um, is this the first time this has happened or have you had a history of this?

Do you actually have an erection during this? If you do, is it because you already had an erection, or because doing the exercise causes you to have an erection and then ejaculating, or do you ejaculate while flaccid?

Going to the doctor would be he best recommendation, I doubt any of us here can really explain how to fix this problem

omg, just get a home gym and enjoy those workouts, lol!
