You can't get HIV from kissing on the lips, so just kissing cheeks and fondling boobs are not a risk for HIV. HIV and STD don't ooze out of an infected person's pores. You can't get STD from kissing a cheek either, or there would be a lot of kids infected from people who kissed them.
Because of the above, tests ]would be a waste of your time. You are free to go beck to your happy life.
