I would like to know if it's a myth that bareback sex is less risky for the top than the bottom.
Insertive anal intercourse, that is, the top, is about 10 times less risky than receptive anal intercourse, or the bottom. An HIV-negative bottom has about a 1 in 50 chance of getting HIV infected after one act of intercourse with an infected partner. As a top, that chance is about 1 in 500. Using condoms cuts that risk down substantially. STDs like gonorrhea, chlamydia, syphilis and herpes can increase the risk of transmitting HIV to either partner.
To your health,
