How do i have a safe felatio or blowjob without getting diseases?

Condom & dental dam: Great question! seriously! it's really too bad that we don't promote safe(r) oral sex, assuming that it's safer than other forms. Anyway, check out following references: http://www.Nakedtruth.Idaho.Gov/dental-dams.Aspx, http://www.Hiv.Va.Gov/patient/sex/condom-tips.Asp & http://goaskalice.Columbia.Edu/where-can-i-get-dams-oral-sex in no particular order. Have fun!

Use a barrier method: In order to prevent the transmission of stds you have to avoid contact with any skin or body fluids. For fellatio some people use Saran wrap to create a barrier, or dental dams (thin material that dentists use to create a barrier in the mouth. A condom can help reduce risk for transmitting disease, as long as only the portion of skin covered by the condom is touched.
