Substitute for erection and ejaculation. [I Love Nipple Torture]

I have discovered that I can get a similar mental thrill without getting a hard on or spurting cum by maintaining my nipples in a super sensitive state so that I respond to the slightest touch. My wife has helped me by encouraging me to torture my nipples with clothes pins and other clamps. Her reactions to me being so obedient as to inflict pain on my own body emphasise how much control she has over me and spreading the word to her friends of what a sissy I have become maintains me in a truly submissive zone.
I accept that I am no longer a man and have started wearing a micro mini bikini on nudist beaches. The bra is open to expose my nipples and the thong exposes my miniature penis and empty ball bag. My wife likes drawing attention to me and discussing me with complete strangers while I just stand there without saying a word until prompted by my wife. She likes getting nubile young ladies to try and get me excited and I enjoy them laughing at my impotence.
