Female led relationships discussion

Hello everyone, my Goddess/Wife and I just finished watching this video:

and decided to pick up some lanacane for a trial run. Does the quantity we got look right based on what was shown in the clip? Do you have any tips for applying lanacane while she’s inside me? Cheers, sissyjazmine , ) P.S.: We’re also planning to grab a plastic vagina soon. Yikes.
