This is a funny question. I want to get topped by these Tgirls with big tools, but I am very tight. Should I try taking a vicodin to help ease the pain? 
It makes me think of corny old jokes like 'doc it hurts when I do this'
There's lots of sex advice material out on the internet that's actually quite useful. If the provider knows what she's doing, she'll help you relax and accommodate you. (I am a fan of well-lubed fingers, myself.) It's not a good idea to just try to shove a cock in there and bang away.
If you really want to bottom, it takes work. You need to use toys to loosen yourself up a bit. Start with smaller ones and work your way up. I have a long process that I go through when I bottom so that I'm ready. I cleanse myself thoroughly (this process can take an hour or more...) with warm water, then start with a string of beads, work up to dildos, then plugs. I work up to a very big plug and just leave it in for about an hour. I replace it with a smaller one when I leave to see the girl and I leave that one in until I get there. I visit the bathroom as soon as I get to the girl's place and take it out. It makes it so much better knowing than I'm clean and loosened up a bit. If you really want to use drugs during a session, poppers are better than vicodin. Poppers loosen the sphincter muscle and make you all horny.... I could take a 2x4 up my ass on that stuff!
I don't have a 2x4, but I've got a 6x2 I can sell ya!
Seriously, though, I've heard that cold water can work better, for an enema, because it will make your colon cramp more. I guess that's supposed to get things moving out, a little quicker?
Hahaha. Yeah, a 6x2 is my kinda number! I've used both cold and warm, warm works better for me. I suppose the caveat of "this anal cleansing/ butt loosening routine may not be for everybody" would work for this post!!!!
While I'm not new to bottoming, I've never tried poppers. Can someone explain exactly what they are and where to find them? Willing to give it a shot.
Thanks
Poppers are an alkyl nitrite. They used to sell them in little bottles at flea markets, head shops, sex shops, etc.
They've been labeled as "Rush!" and "Video Head Cleaner".
You inhale it and it makes you feel like your head is about to pop, but supposedly it relaxes your anus and throat muscles, for...well, you know....butt fucking and throat fucking.
"jungle juice" is another brand and Hustler stores here in LA carry them.

All I can say lots of four play and lube
