I lay down for about 15 minutes before I insert a toy and start my session. The anal sphincters are strong and standing probably helps keep them tight on their own to prevent leaks, but I lay down and relax and start to get into the vibe, and then immediately start my session once enough time for the melt to melt has happened
@vicegrip I do my prepping prior to insertion of booty melt (douching, floor setup, lighting, mirrors, lube and toys located near the session site). When all is ready including 30 minutes after douching, I lay on my side and insert the melt. Then I wait 20 to 30 minutes for the melt to start working. Then I insert my smallest toy and focus my attention on the anal and prostate sensations. After a few minutes, I change the toy to the next larger one, and so on, up to my larger vibrating and thrusting toy. Settle in for a long, enjoyable, fun session of asshole play. I sometimes end my sessions with an explosive cum shot, unless I'm practicing semen retention, which means I don't cum for several days to a week or more, if I can hold it. With semen retention, I have tons more energy for things other than sexual play and cumming, and I feel stronger overall.
