Successful and pleasurable bottoming takes time and practice through dilation exercises, training of your self-awareness, and control of the pelvic floor. The good news? Of course, it may be uncomfortable at first and you might initially question how there could ever be pleasure in it — something that happens with vaginal sex the first time as well — but like anything it takes practice, patience, and following a few simple guidelines to enhance this sexual practice. I often tell patients that great bottoms have been doing it for quite some time, with many first experiencing it in their youth. Unfortunately, no one showed us the right way to bottom in our high school sexual education class. Begin with dilation: Get yourself an anal trainer kit and start training for dilation two to three times a week for as little as five minutes each time.
Background of the Invention  This invention relates generally to oil and gas exploration, and in particular to forming and repairing wellbore casings to facilitate oil and gas exploration. The borehole is drilled in intervals whereby a casing which is to be installed in a lower borehole interval is lowered through a previously installed casing of an upper borehole interval. As a consequence of this procedure the casing of the lower interval is of smaller diameter than the casing of the upper interval.
