I've found the best time to tell someone about a fetish is after the 3rd bang. You like each other well enough to have sex, but still have an opportunity to air things out before you're "set" in the relationship. The trust issue is important, so for sure don't say "i want to cut off your dick" to anyone you just met. Unless you met them on this forum.
Since true penectomy (for anything other than medical reasons) will probably land you in prison, stick with knifeplay. It's exciting as hell and you can come back and play more. Try a blade in bed rubbing it on his skin... start at the chest, go down, and refrain from actual bloodletting. See how that plays out. If he's into it, you'll know.
Thank you for the advice, like I said earlier, my sex life has been not very interesting so far. Knife play sounds like alot of fun, playfull is my comfort zone, and it would be a fun, funny way to get a reaction, rather than a backfire. Actually the thought of knife plat really turns me on
I couldnt imagine ending up like one of those women on the news that got arrested for cutting their husbands penis off while he was sleeping.
