In Soft Swap, oral sex is generally considered as good but full genital penetration is not. This may not be the case for everyone though. To some people, Soft Swap may mean kissing only or touching only with no oral or genital penetration at all. That's why it's important to ask people their rules and not just ask if they are Full or Soft Swap. Most of the time, Soft Swap is like foreplay, and ends with same room sex with your own partner.
Full Swap can be an even broader definition. To Wifey & me, our definition of Full Swap Swinging is "Swapped partners, same room sex only, oral and full penetration WITH CONDOM are good and encouraged. No anal." But that's not the way it is for everyone. We have Full Swap friends that only play in separate rooms. To some couples, anal sex is also considered part of the Swinging repertoire.Most Full Swap couples would not consider sex without condoms or anal as part of the usual Full Swap experience, but playing in separate rooms is common.
