"Condoms are HIGHLY effective against pregnancy.
Condoms are HIGHLY effective against HIV.
Condoms are really close to useless for protection from HPV/HSV/Gono/Chla/Syph"
Absolutely! We have met several couples who have acted like the use of condoms is some kind of magic talisman against any and all forms of sexually transmitted bugs yet will begin the session with all kinds of behavior that makes the use of a condom for actual sex to be a bit silly in retrospect. It amounted to sexual security theater.
Now if your use of condoms during sex is to prevent pregnancy I can totally understand that position but for the couples in question, pregnancy wasn't a concern. If you're concerned about HIV, again I understand but HIV is not prevalent in the heterosexual population and in the swinging community in general.
As others have stated, no one is suggesting throwing caution to the wind but for most people the perception of risk associated with bareback exposure doesn't match up well to reality. Vetting of your partners by getting to know them first before you jump into bed and not playing with bi men goes a long way to keep you safer in the bedroom than believing that a condom will prevent STI's cause that's what the TV told me.
Bottom line can be summed up as such. If you feel reasonably confidant that the people you're having sex with aren't fucking everything else that moves, aren't engaging in activities that could bring in HIV and if pregnancy isn't a concern then having unprotected sex isn't as big of a risk as many would have you believe.
