Bondage

Hi there, I could use some advice. My friend and I have had a close relationship for quite some time (just so you know, I’m male and she’s female). The other day I discovered that she also enjoys bondage, which made me want to bring it up. However, I wasn’t certain whether I should say something because our friendship is important to me and I didn’t want to mess it up; on the flip side, we could potentially become a new couple for this activity together. Any thoughts would be appreciated.:?
