You cannot perform an at home circumcision. You can end up really messing up your penis, and that can be quite an embarrassment and disaster, as the penis is one of the only free pleasures allowed to guys, and it does deliver in that regard. If you want a circumcision that badly go to a doctor; but do bear in mind that circumcision has it's costs, other than the money. First off, the foreskin, which is full of sensitive nerves, is going to be removed, meaning you'll lose a good deal of sensitivity. Secondly, the glans (head, helmet, etc.), which is always protected from exposure to rough materials like clothing and whatnot by the foreskin, has to accommodate for the removal of it's protection, and thus is forms a thickened layer, similar to how hands will callous with constant work, and this thickened layer will further reduce sensitivity. And also, uncut guys need no lube to masturbate or have sex, the foreskin provides a natural glide. Having no foreskin for this glide means you'll have to purchase lube for masturbation and sex, meaning that you'll have to keep spending money to enjoy your penis, which will inevitably cost you way more than the initial circumcision and of course way more than remaining uncut. Also, in regards to the purported health reasoning for circumcision, those are skewed and false. Cleanliness leads to lack of problems, as simple as that. The eradication of a 5 second wash is nothing worth spending so much money over. Also, in regards to the supposed STD "resistance," this is utter crock. STDs can just as easily enter your body through your glans as your foreskin, and also just as easily enter through the skin on the shaft of your penis, meaning that the removal of the foreskin will not give you any resistance whatsoever to STD contraction. Condoms, not circumcision, prevent the spread of STDs. So, think well on these costs and consider if you truly wish to get circumcised. I wish you the best of luck in either decision, and I hope it is a choice you are making on your own accord, and not from the pressures of others.
