@DrewDad,
I found this that supports your opinion:
If you think a female can not force a male to get an erection against his will, think again, you have little (to no) control over that part of your body with your will power.
Think it can never happen? see abducted adult male abused by females among others, but please don't say "i wish" unless you want your testicles destroyed as much as his.
Think you could never be forced to gain an erection? Wait till the most important football match you ever want to watch is on TV, then see if your partner can distract that part of your body against your will
You will lose every time.
Think an unconscious (drunk or drugged etc ) male can not get an erection ? ... never woken up with morning "wood" or it happen on a bus or at the supermarket, or work, against your will .... the mind has little control on getting it to just go away.
People who suffer from impotence often just need a vacuum pump (or a mouth) and a rubber band and it will stay hard as long as they need. Also see here .(BBC Horizon program).... if they can get a medically induced unconscious rhino, gorilla, etc, to ejaculate what chance does that give a man ?
