The best lubricant from Germany! I also use it in my car engine and actually get better gas mileage! You can find it in any good quality adult store or your local Pep Boys!

Wilma!

Don't worry... I won't tell her...lol..just that your handle brought back some funny memories of Fred and the gang.
Don't know much about lube but here's some words of wisdom:

To do is to be. - Descartes
To be is to do. - Voltaire
Do be do be do. - Frank Sinatra
Yabba dabba do. - Fred Flintstone

Cheers!

Whatever lube you use, just make certain that you go s-l-o-w-l-y until the lady tells you otherwise.

Eros lube is awesome!  A little goes a long way.  Butt, if she needs more, use more.  There is no such thing as too much lube for anal sex.

Start with a finger to get her relaxed and ready.  I recommend that you start with doggy style.  Don't move at first.  I repeat, don't move at first.  Let her control the penetration by sliding her ass on your cock, slowly taking it in at her own pace.  You'll probably want to push, but don't do it until she's ready.  If you push it in before she's had a chance to relax her sphincter, she'll stay tense and it will hurt.  Once she's good and ready, she can let you know (verbally or through body language) when it's time to thrust yourself into her.
