After hearing all these personal and provocative admissions I have concluded several thoughts. I believe the foundation in a relationship is a feeling of trust and communication and with that, you can venture with your partner in more depth than the daily obligations. You can physically and emotionally fulfill each other's desires.
As for our more frisky fellows, I feel that people can enjoy themselves in these kind of activities because they get to let loose, let go of structure and embrace the feeling of freedom in sexuality without being judged. Is it everyone’s cup of tea to partake in such crazy scenarios, probably not, but if it makes people feel happy, then go for it. Communicate your desires and explore yourself and the world of XXX!!!
