What Are The Chances Of STD Transmission Through Inanimate Objects?

Hi there, I feel as though I am probably paranoid. But last Monday, (5 days ago) I was at the mall trying on bathing suits. There were a few that I tried on without underwear. I realized how dumb and unsanitary it was after the fact. I then started to worry I could ve caught an STD. I started searching online and Ive found several sources that state its nearly impossible to get an STD from trying on a bathing suit without underwear but that scabies, pubic lice or crabs could be spread through bathing suits. Is this true? Is there anything I should be worried about? I don t have any symptoms and the sources I read stated that you could see symptoms anywhere from 5 days after trying the bathing suit on up until a few weeks later. Is this true? Also do some people never see symptoms but still have these STDs? Please let me know. Thank you.
