Barrier methods, such as latex condoms, reduce the risk of contracting diseases. Robin Corderman, Planned Parenthood's director of community affairs, said people should use latex condoms and avoid animal skin condoms that have large pores, letting organisms through. People need to use appropriate lubrication - not petroleum jelly, Corderman said. People should use only products meant to be used with condoms, specifically Asteroglide and Probe. Spermicide and foam can also be used with condoms.
Dental dams are another barrier method.
Corderman said dams provide a physical barrier placed in front of the vaginal area during oral sex, preventing transmission of bodily fluids. A diaphram is a soft rubber oval that forms a seal over the cervix, making a barrier against sperm and organisms. Preventative measures lessen the risk, but if you feel you may have put yourself at risk for an STD, you should seek help. You can't leave it behind. This group provides facts and information on STDs.
