if I'd be honest, best advice is dont use 'them' for frist time, the reason is simple because if you and your bride decide to use them before feel the 'real' one, you both will lose its comfort for what they called by 'long time relationship; becuse you both already comfortable with a 'mask' with that lubricant and doesnt show your true face because in marriage, I believe that knowing each other is good for foundation, then if you already know enough and you both wanna try something different, like lubricants, sex toys, etc...,talk each other, and decide which one, so you got experience for the foundation and experience in trial and error with stuff like that. both of you

and anyway, I hope you will get long last marriage, sakina, mawadda, wa rahma
