Safer sex vs. safe sex

I noticed in the JAMA article about topics doctors need to cover to prepare for barriers that LGBT patients face, safer sex was on the list. Wasn't familiar with that, so I googled it.

It's another term in our ever changing lexicon. It is now used instead of "safe sex."

"When people speak of "safe sex" today, they are referring to abstinence. Abstaining from sex and sexual play is the only sure method to avoid catching an STD and to prevent an unplanned pregnancy. Although it may not prevent a pregnancy, having sex within a committed, monogamous, long-term relationship with someone who has tested free of any STDs is also generally considered to be safe sex."

Actually, because an inflected comparative such as "safer" or "handsomer" or "brighter," would mean "more than safe," or handsome or bright, the term "safer sex" to mean something less safe than no sex (abstinence), really makes no sense at all. This might be difficult to understand for a non-native speaker--or even a native speaker!
