Oh, honey, share the love!
Haven't we all learned moves, techniques, and what our sexual preferences are from all our past lovers, which teaches us for the next person? I don't see this as any different. As long as your partner doesn't mind you sharing details with your hubs, it all sounds great. Bring it home -- what you do with each person will still be unique because of that person's energies. It's not betrayal, it's making the most of a rich and varied sex life! Enjoy!
