Yeah dude you got rocked by your first time, there's really no need to roll harder than that.
What I recommend, though, is this ... about a month from now, you and your wife should take a Saturday afternoon all to yourselves, sleep in, and take a pill each in the early afternoon and just lay around the house all day hanging out and fucking and generally enjoying yourselves. You won't get hit as hard as you did in Vegas when you were drunk and partying and carrying on all over the strip, so you'll be able to just chill and have a really nice time with your wife and talk about shit and have some great sex, and you won't even feel too shitty the next day because you'd only be taking a small-to-moderate dose. Don't drink or do any blow or anything ... just roll and hang out together. You'll have a great time.
Just don't get freaked out if you can't get hard while you're peaking on the roll. That's totally normal, it's just the drug. When you're coming down a bit, though, you'll be able to have sex for hours.
