So you sit there in a tub of hot water with your shit floating by as you fuck yourself with a dildo? I'm going to have to advise against this approach. You are setting yourself up with a perfect environment to get a MRSA, a highly drug resistant skin infection, aka Flesh Eating Bacteria Infection. If you survive, then often times you are left with a severe scar, or worse, it eats yo ur entire nose off.
Also, what's the point of fucking yourself so feverishly with a dildo when you're bout to go get the real thing? Personally, I want a hole that's nice n tight that I get to make blossom and relax and open up with my flicking wet tongue, then gets gaping after I plunge my prick in deep. I hate big loose mancunt thats so stretched out, I feel like I'm just fucking air. I will agree that a dildo deep insertion test is a good idea, aka the Dip Stick Test. Remember, a simple plain cold water enema, not warm water, and Fleets Enemas should be avoided as well. Do not apply repeated thrusts w dildo, rendering it useless ane deified into "gaping pussy" status. A few slow, deeeep, and careful insertions of ur dildo to grab that leftover bit o' lunch, then preserve that little pucker til your date arrives.
