Sex. Gross? I'm totally not on board. I need sex like I need air, water, food, and love. While I completely support your rights to do what you will with your life and time, I have no idea what you're talking about.
I love everything about sex with whomever I have sex with be it my partner, a long time lover, or a new fling, poised to burn out in a moment. I like sweet, fast, slow, kinky, vanilla, straight, not, multiple partners at once or just one to dote on, whatever. Orgasms are a joy and making a partner climax is one of my favorite things to do in life. The tension before you kiss for the first time. The thrill as your body responds to their desire and theirs does likewise. The sharing of pleasure and desire mixed in a cauldron of bodies, friction, and sensations. The power that you hold over them and they over you.
Exploring sex is a fascinating pastime. Finding new ways to excite and arouse, pleasure and be pleasured. Finding new kinks that you didn't know that you had or finding a partner who shares one of your favorites. Introducing them to your own private world of sensuality is one of the most openly trusting and sharing things that you can do in this world.
Ahh, I completely need sex and cannot imagine life without it. Maybe when I'm old and too frail to want things like that but... no, no I don't think I'll ever get tired of it.
