I'm sure it can because any form of stimulation can cause a man to get an erection, even if it is unwanted. Still, this whole thing is dumb lol. I don't think this guy realizes how dumb it is to blame a company for having seats that just so happened to cause him to get an erection when he should be blaming his own body lol
I think you're supposed to go to a doctor after 4 hours.
I'd say call a doctor if it lasts longer than an hour for a professional opinion lmao.
