What is the difference between soft swap and full swap?
A soft swap excludes penetrative intercourse with anyone other than your primary partner. It typically allows kissing, oral sex, mutual masturbation, and same-sex contact between the women, with vaginal or anal sex reserved "in-couple". A full swap (or full swing) includes penetrative intercourse with the swap partners. Couples often start soft and move to full once trust builds, though many stay soft long-term as a stable boundary.
