1. Swipe down
If you've ever happened to or purposely been in the shower or under the bathroom faucet and found that running water through Vagina would give you a better feeling, then you should definitely try aiming Vegina at a jetted pool or hot tub. (importantly, make sure no one else is around!) Now you can try it out, cold or hot water is a matter of personal preference
2. Electric trio
Spend some money on a really great toy, or buy a few more. You can choose a toy that stimulates the tongue, or a toy that stimulates the G-spot to satisfy your internal needs. Even if you don't think you're that sensitive, trying these will change your mind.
3. Double cycle
Circling one finger around the private part, at the same time using a finger of the other hand to circle around the private part entrance. The hand at the bottom is a little slower, give yourself a process of adaptation, and when you really have fun with it, you will be overwhelmed by your newly learned abilities. (If you and your partner need inspiration to know what a woman thinks about being touched, then you both need to get over that mental block and watch a little movie.
4. Pretend to be a lover
Get a fake pencil on a chair or bed and rub it slowly. Rub your butt against the toy and moan loudly (remember to close the window first, of course). Even if penetration doesn't bring you to orgasm, it's a great feeling.
5. Mirror grinding
Grab a large tube of lube (you'll need it) and sit in front of a waiting mirror. Dab some lube on your nipples and play with your tits, sliding your hand over them to find your favorite pattern.
Apply more lube and use more on the abdomen, slowly extending to the vulva. Look at yourself getting wet with your sex drive, don't think about other things, just focus on your sexiness. If this sounds odd to you, then you need this method in particular.
