It Hurts
Sometimes I'll just be minding my own business when I'll suddenly get these extreme pains in my abdomen. Then I know I have to take a major dump and I'll get a huge erection. If I don't go right away I'll start getting nauseated and feel like throwing up until I take a crap, after which I'll finally go flaccid. This is extremely embarrassing at work, esp. having a huge boner and heading towards the bathroom. Can't imagine what my co-workers think ... oh there he goes to masturbate again. Is it normal to get an erection when you have to take a major shit?
I am a female and have no idea what you are going through, but maybe it is because just as the excrement is ready to pass, you are getting pressure stimulation to your prostate (from urine coming down too) or erogenous zone? Or you could be getting this tremendous blood surge down there, causing the erection.
As for the nauseous feeling before evacuation, I have heard of that before for sure, usually with constipation or larger than usual bowel movements. Maybe it's from the "peristalsis" process of moving all that junk along your intestines. Just guessing.
It might all be some kind of psychological problem, or a fetish with the feeling of needing to poop right away.
Am I helping or making you feel worse?
P.S. NO EJACULATION!!!!
I have seen some men come out of the toilet looking quite pleased with themselves
like having anal sex. but in reverse and with the cock coming....
why not get one of our coworkers to help u out with that erection!
