wanna ask that If a visited a place & next to that place is a clinic outside which some syringe covers & caps are thrown (appearing old) & I am wearing shoes & I might have stood over any syringe cap or cover ( as far as i remember i didnt stood on any but i am still taking a chance) , its rainy season but the day is sunny, I come back home with shoes on & go to the bathroom to wash hand ( it means I walked inside bathroom with my shoes on). After 2 days I take bath in that batroom (i am barefoot) & wear my undies such that a part of my toe may have slightly touched the insides of my undies & then I masturbate on that very day inside my undies (i know it very disgusting) . So is their any chance of getting STDs like hiv n all..its like i brought virus with my shoes ...they were there for 2 days in my bathroom ....i take bath...the virus stick to my soles...i put my feet inside undies & transfer the virus with my feet to the fabric of undies & then i masturbate & my penis sucks the virus through the semen i ejaculated in my undies
