I'd like to think I can trust my wife of 20 years so we don't use condoms as we have other contraceptives in place.
Wouldn't even entertain the idea of swinging without protection. To be honest if we know, we don't play with those that choose to have unprotected sex with casual partners either.
Always safe with swingers. But hardly ever with partner. We know we are both clean only times use with partner is if for some bizarre reason I've missed injection or I've been on antibiotics that can cancel out the injection x
