If rimming is involved, then shower ahead of time is a must for me.

Still a virgin, considering to bottom, this topic is a nice help, any advices for a first time bottom?

Douche and prepare with a dildo.

If you're a true virgin, you may bleed so you want to practice with small to large sizes.

I've bottomed before and it's a literal pain in the ass.  I personally need to start preparing 2 hours before sex and that includes using a shower sprayer with a special nozzle to clean out my intimate parts.

Reading all the comments, up to bottom, interesting facts… but in some way, scare me out  :afraid:

lol right!!!

I clean out for far more than if I was just getting fucked, I regularly get fisted, so I need to have a good deep clean
About 6 hours before play I take a couple of loperimide capsules to slow movement down
2 hours before play I douche well using a nozzle attached to my shower (until I run clear)
1 hour before play I have another loperimide
30 mins before play I douche well again (running clear again)
I can then play for hours without any issues

Certain foodstuffs should be avoided, especially peanuts! Quite a few guys I know have issues if they had cooked onions the day before too

Woah! That's so much prep

I prefer to smear bacon fat on my pants leg before calling Duke to cum do his thing.  If I need a thrill, I wear shorts and apply the bacon fat directly to my shin.  He does oral foreplay to my leg before giving it the ole' "1-2 I'm humping you:.

Haha, well … that's a very interesting contribution to the thread, sir. 

Reading through the posts, I can see a trend, which I can acknowledge as my own too:
There's a difference between prepping when in a relationship and when hooking up.
Most of those who werent very focused on enemas, diet, waiting times, fasting and food abstinence, were those in a relationship. While those appalled by lack of enemas every 2 hours, where mostly those into hooking up.

When you're going to hook up or getting a sex date, of course you can plan everything. And good for you. But if you're in a relationship, it's kind of impossible to plan a fuck (and honestly, to me it's also sad). Things are more spontaneous, and spending a lot of time together (and often living together), offers countless chances to impromptu humps. Fortunately, I live in a country where each and every bathroom has a bidet, and it's common practice to have a thorough cleanup after you dish out your dishes, and it always has been all that was required to never have any problem striking an ass.

And, to each his own, but when I hooked up, I never got my dick fudge iced, also because I always used a condom. Cause, honestly, without a condom striking oil would be the LAST of my worries.

Recently I've tried bottoming but it's been spontaneous - but luckily no drama… but it was constantly on my mind. I've eaten a plant-based, whole-food diet for years which results in awesome bowel movements so don't even have to wipe most of the time - just a test square. I've never preped before being bttmd but am definitely prepared to. I occasionally do a mini-colonic anyhow with a rubber ear syringe + purified water, repeat - all the fluoride, chlorine etc in tap water is not going to be great for the butt. I also sometimes use weak organic coffee or spirulina for different benefits.

And foxyboxerboy, instead of thanking whatever god there is (or isn't):

I'm a top/vers and would never let anyone near my hole without douching.  Its common courtesy to do so, more like it should be common sense.

Solid 8 here and almost every time i "strike oil" as they say, its a result of some inexperienced or just ignorant bottom who didn't douche.  In fact i've sent a few out the door for refusing to douche.  Now I can get pretty kinky, no vanilla bean here like so many must be on this forum.  I like to fuck a studs brains out, rim b4 and after penetration, maybe  use a toy on the boy if he likes.  i couldn't do any of what you see in "good" porn without the btm properly preparing.

Now the guys a few posts back, AMEN!  the education on how is what some of these guys need.  If you think your gonna come over and turn my dick into a shit stick then quite frankly SEE YA NEVER AGAIN! 
HOWEVER, if i know you made a conscious effort, then no biggie, my clean shower shot is available for you, go check yourself and we can continue till i seed you proper. Then that grin of "thats what i came for" ear to ear is what i love to see.

seriously tho, i've gotten a uti, even terribly sick to my stomach from dirty boys.  Dont be a dumb dingy bitch.  and for the record, in my countless nights fucking sometimes hours bareback, HAVE NEVER contracted an STD.  Boo yah bitches!

and for the guy who walked ya through step by step on how to douche, thank whatever god there is for your post.  its guys like you that makes me look back on life say wow, i've fucked my way through my twenties and could die tomorrow fulfilled not missing a thing.
