do i need more hiv testing? Can i just move on?

all i can say is... in my life of being sexually active.. i been bad! I've had alot of partners. i had instances w/o condoms, last time i had unprotected sex was 2 years ago, and i was too afraid to get tested, then 5 months ago is when i had protected sex.  I recently got tested for hiv, and other stds, all negative. Im so happy of the results but still freaked out. Im not gonna have sex for a looong time. But, being that i've had multiple partners in the past...do i still need testing even though my latest results were negative? I hear people get tested even though they arent sexually active.

A test 12 weeks (3 months) post your last exposure is conclusive, so if you tested negative at 5 months post your exposure as you have suggested then you are in the clear.
