If you explore yourself you have control over you actions. Climb into a tub of hot water (or a shower or on your bed) and relax. Then with you fingertips explore your genitals and thighs, gliding around to feel what it's like. Then bend your legs and slide your fingers down between them lower and deeper, past your testicles. Touch your anus very lightly with one finger. Then with several. Push down a little- how does it feel? If you like that, try masturbating while pressing several fingers on your ass.

Now you've made contact. If it feels good there or if you sense that it will, keep exploring. Don't push yourself to do more than you want at any one time- pace yourself comfortably, but try to tune in on your rear; discover when it's tight and when it's loose, and how you can control this.

At some point you'll want to take the plunge, inserting a finger inside. It's a remarkable discovery that you can do this, and it opens up a world of new sensations. Be aware that the rectum is a sturdy, flexible organ and can't be hurt by fingers, a penis or other similar objects, unless you violently intend to do so: if you don't make your finger force your ass, or your ass force your finger, they will work well together. Sharp edges like fingernails can scratch it, and that's not good, so be sure your nails are well trimmed and filed first. The bottom line is if it can take all your excrement in its many shapes and sizes, it can take smaller things like fingers and cocks.
