I Want To Tighten My Vagina Walls. My Boyfriend Said

I want to tighten my vagina walls. My boyfriend said I'm too loose there that he's not getting any pleasure. I recently had breakup with him.
I heard of applying amla juice and some tightening gels there which gives tighteness.
Is it true.?
If I don't have sex for 1 year or more. Will my vagina get tighter that my future husband won't get to know about my past. I want to keep my future husband satisfied and happy.

Waiting for resolution.

Thanks in advance
