Welcome to Healthcaremagic Forum
The chances of STDs or Blood borne infections are very minimal in here , as most of the organisms which cause the STDs do not survive in the blood out of the body not more than for few minutes. Hence do not worry.
But there are many other minor infections like ones those caused by fungal spore and cysts , through washing of the part after the procedure would help better. Also there is risk of tetanus
in such procedures , if you are vaccinated for tetanus it then it will take care . every time you get these procedures done make sure the area is wiped by a antiseptic solution like cetrimide always and then washed in clean water, this will remove the chances of infection to very negligible.
