oh and as far as infection goes.,.,.easy:
no unprotected sex until healed
clean with the appropriate soap (provone,etc.) daily
keep your filthy hands off your dick, make sure your hands are clean if you are gonna jack off or whatever
drink lots of water and piss a lot cause piss is sterile and heals and cleanses it
no lube until healed as it attracts bacteria, even water based
daily salt water soaks (1/8 t. sea salt mixed with 1 cup of warm water) i use a clean disposable plastic 9 0z solo cup-just dip ur dick in for 10 minutes
wear clean clothes (underwear or whatever)
do not use antibiotic ointments or antibacterial commercial soaps
do not dry off your cock with your bath/hand towel, use a clean paper towel and dispose.
i know this sounds like a lot but it's not and it's common sense
