NOTHING that you have described put you at risk for contracting hiv.
hiv is not transmitted from environmental surfaces or inanimate objects. it is also NOT transmitted through masturbation.
no risk = no test
no risk at all
HIV is transmitted through:
1)Unprotected penetrative sex with someone who is infected.(unprotected vaginal / anal intercourse )
2)From a mother who is infected to her baby; this can occur during pregnancy, at birth and through breastfeeding.
3)Sharing needles with HIV infected person during IV drug intake.
Always use condoms and never share needles
