The very first essential to sensuality is lubrication. Hands down, the smoother things move the better. Even for those of you who don't want to experiment with anything else, lube may be your best friend. One great thing about it is variety. Lube comes in different scents, flavors, textures, warming, cooling, or plain; there is definitely room to try others if you dislike one. Personal recommendation: Jo. If you have no partner and are doing only solo sessions, lube will increase your pleasure, so if you are having orgasms there is no excuse.
The next essential in a pleasure kit? It depends on the person and what they're into, but if there is a woman involved I recommend buying a vibratory device of some sort (this may change her world!!) and if you are a man uncomfortable with her receiving pleasure from a toy then you should rethink this: if she isn't getting it from you, she's getting it somewhere else, would you rather it be a vibrator? Of course to you one-night-standers you probably aren't involving toys with your partner, but hopefully when you're alone. Men, you can benefit from a vibrator also, ever heard of a vibrating rubber vagina? Bonus: the bullet in there can serve as a pleasure tool for men and women! If both partners want to enjoy a vibrating sensation at the same time, they simply need to turn to the cock ring. Just make sure the ring itself is not too small or large for the base of the penis, or it will not work.
There are so many sexuality enhancers that we can take advantage of, and being broke college students there are ways to create steamy scenarios. Ladies, the next time you hop into a shower together, wear a thin white top. Seeing your breasts like this will likely drive your partner bonkers, and is a lot cheaper than a "dress up" outfit. The liberator, a foam wedge used to hold the body in position, is a tool everyone should also have, but they cost around $100. A pillow provides an adequate replacement, but you may need to readjust a few times.
From tame to kinky sexuality is a part of a healthy lifestyle, it is important to be honest with yourself what you like, want, and need out of a sexual relationship. There are so many different lifestyle choices one could make regarding their sexuality, don't deny yourself your true sexuality.
