usually once a year but remember there are 3 months window period after sex.
I'm pretty sure with AIDs which is probably the most concerning of all STD's there is a 6 month window you need to wait to be sure, getting tested at three months and you get back a negative, don't be to relieved just yet.
So Definitely at least every 6 months, anything more the that is probably too frequent.
