He's right. Sex is sex. Tickling is tickling.
If, however, tickling happens to arouse you, and you're married, and your partner knows this is true, there are complications. If, like some of us, you CAN play without crossing the "you're cheating" line in YOUR relationship (and your mileage will vary), there's no problem.
If your partner's jealous, dangerous.
Yeah, though. Had that requested of me repeatedly for a long time. Before we started gatherings. Quite a lot after they began.
