How many of you guys try and warm up a girls asshole before you start pounding away?

Do you use your fingers? Girls, do you use a butt-plug before a session to prepare?

Lately I've had a string of guys who are more than well endowed and have not even thought to try and warm me up. I'm quite capable of accommodating a man of just about any size, with the proper warm-up. When a guy asks to fuck me, I don't want to say, ok but you have to warm me up first, because usually by then the hard-on is gone, and its never fun when someone with a half-hard cock tries to fuck me.

Also...guys, when you plan on bottoming, do you give yourselves an enema?

Preparation is key in all sexual endeavors.  I could not expect you to take a cock without foreplay......and foreplay is often more fun than the act itself.....so with me, you would be warmed up.....properly......and wouldn't even think about it before we had sex.

Of course preparation is a two-way street.  I expect my date to be clean and fresh, and I, in turn, am responsible for my shower, mouthwash, and of course cleaning my plumbing.

If I didn't think of my date and take these steps, the time we spend together would be much less than it could be with a little care on both of our parts.

and Mandy............the preparation of your asshole could involve fingers, tongue, and whatever else is appropriate for the chemistry between couples.

i admit i forget to finger a girl before topping her. And i tend to think the lube poured down the drain would be good enough. (the girls actually  grease themselves) i usually prounce on her after giving her a good hole-licking before the lube job and just about every girls that i've topped have been pretty much
"broken-in". If i feel the hole is a little tigher than usual,or feel/hear that i am discomforting her, then i usually ask the girl if she is ok and react upon her response. If she responds "it's ok" or that's fine, sweetie" then i feel comfortable and keep up the pounding.

i still cannot believe that that i hear there are cases where a guy doesn't "clean" himself before a ts-topping session. Are these men just naive about enema/douche methods ?

yes and yes

Never performed an enema and never had an issue at all. Of course I make sure that I am not "prairie dogging" it either! LOL

When I bottom, I make sure to give myself an enema so that we both have a great time.

I usually give myself multiple enemas hours apart, sometimes starting the day before.
