Men and women aged 55 to 59 were most likely to have a sexually transmitted infection in a recent study of the over-45 crowd.  Increasingly likely to be single, mature adults are unfortunately less likely to use condoms.  Just because you can’t get pregnant doesn’t mean you can’t get genital warts or herpes, people – use condoms!  C31G and Buffergel (www.reprotect.com) are two vaginal gels under investigation right now that women will be able to use to block STD’s (and possibly pregnancy as well) starting in 2011.
