Am i at risk of STDs?

No your not at risk this way for the simple fact you are listing alot of STD's which you catch through unprotected . Now as far as hepatitis you can catch that from coming in contact with a person that is infected without ual , and HIV and AIDS aren't the same. HIV is the virus and AIDS is whats made up of the virus (when people are known to have full blown aids as they say!) And even with HIV it dies once it hit the air especially if it didn't come in contact with a person or a persons blood. It's good to be cautious of all STD's and to be sure your doing everything to be safe from them because they are real and they are out here.
