This is powerful information if you use it properly. But it takes some finesse. What you don't want to do is move forward like a complete oaf, trying to jam a finger up her back door with no warning (and worse no lube) and concentrating only on your own thrill of venturing into new territory.

No.

Anal sex (whether stimulation from a finger, a toy, or the full Monty) is still a taboo subject for many people (and illegal is some states). If you find that you can't bring the subject up directly with your lover than you need to move forward with care and caution. And yes, some women might totally freak if you ask her about it casually, but in the heat of the moment if you play your cards right, she might find the sensation so pleasurable she totally forgets her inhibitions.

But remember I said to move forward with care and caution. Now let me point out why. Unlike the vagina the rectum doesn't self lubricate, it's lining is also delicate and prone to tearing, so no rough cuticles or hang nails, or forcing things to happen - and never without proper lubrication. Let me be very clear here - it hurts like hell.

Also, the rectum is full of very virulent bacteria, so if you touch the entrance, or go inside, you cannot touch anything else before washing your hand with soap and water.

But nothing ventured, nothing gained, and the payoff is worth it.

So let's say you and your gal are getting down, having a good time, and you want to try this new thing. How do you introduce it while in action? Let's say you're giving her some oral action, start by caressing the undersides of her tush with your fingers (always keeping your ears and eyes open for her reactions) slowly moving towards her back door. If her breathing quickens even more, if she starts making more noise, than you can whisper as your fingers inch closer "ever thought of a little extra stimulation back here?"

If she vigorously shakes her head and tenses up, today's not your day.

If she shrugs, or moans but ignores the question, or (hopefully) says something like "yeah, that sounds good right now" don't be greedy - again move slowly. The anus is so sensitive that simply stroking the entrance of it while going down on her will add fireworks. In fact, that's probably how you should start.

And remember to use extra lubricant.

So let's say you'd like to introduce a little more anal play into your routine. The easiest way to add to the action during intercourse is with her on top. With her on top, grinding away, you can cup her ass in your hands and slowly work your way around to her back door again. If she enjoyed the extra stimulation at the entrance, try inserting just the tip of a finger - remember a little goes a long way with anything new you're trying. Don't push further than she's comfortable with you going.

Once you find out that she actually enjoys this sort of stimulation then you can branch out into using toys, and yes, even anal intercourse - but always remember that you shouldn't push her farther than she's comfortable because something that's meant to ad pleasure can end up causing pain.

Now, it may so happen that your gal is the sort who likes fair play. She might just turn around and say that she's more than willing to let you try anal stimulation on her - if you let her try it on you. Be open minded (but no, I'm not suggesting she go get a strap on if you're not ready or interested in that), you have that same pelvic floor region she does, and remember that men have an area inside of the anus (called the prostrate gland - which women don't have) that can actually trigger quite intense orgasms.

You might be in for quite a wild, and enjoyable, ride.
