ADVICE: Ecstasy on date night

For our anniversary GF (23F) and I (23M) have planned to do E for our date night. I have only done a quarter of E before and it would be the first time for my gf. Any advice on how to plan on having an amazing experience and ultimately bomb sex. We would be doing e in the comfort of our home, and since it would be a proper tripping experience any kind of advice is appreciated from any pov.
