Spanking

Get a riding crop. You can use it yourself. Hit as hard as you want. Aim for your labia or clit. Nothing like it. Good thing is, just leave it in your bedroom by the bed and most men will zero in on it and use it on you without even asking.

Get a clit clamp

I do it when I flick the bean. It's kool.

My wife gets off on having her pussy flogged with a horse-hair riding crop that we bought at an adult store specializing in BDSM stuff. It makes her super wet and ready for a good hard fucking, that's for sure!

My husband does this every time we have sex, big finish to an incredibly hot night I LOVE IT

First off, no......it is totally NOT wrong to want that. How to get it is the delicate part, but not because it's wrong ........... it's just because you're uncomfortable asking for it. If you aren't in the kind of a relationship with a man who's open to that sort of play and who you can talk to freely about fantasies and fetishes, then you could always escalate the roughness of the sex with your partner (whether one of your regulars, or somebody you pick up at a bar) -- just slightly, nothing alarming -- and then while you're at it, appear to get even more aroused than you were, and start slapping at or spanking your clit with your own fingers. Do that for a while, moaning more and louder, so it's clear to him that it's turning you on more, and if he doesn't pick up on those cues, moan again and ask him, "Baby, can you do this for me, pleeeeease?", while you keep doing it to yourself, and if he doesn't take over, you could feign begging [men love, love, LOVE to hear a woman beg], "God, baby, I'm begging you to please hit this for me, PLEASE???" If he doesn't respond appropriately, ask him to leave, because he's wasting your time. Go find a man who'll give you what you need and want. They're out there, trust me: you just gotta find them.
