mushrooms don't do that kind of thing to you. What ever is in your brain is what mushrooms work with. So, if you're ok in the head, you'll be ok enjoying a trip and great sex or a great stroll through beautiful scenary.
It's like being given the ability to see what someone who painted a great piece of art was seeing, feeling when they got the inspiration to paint it.

It's hard to be that open on an everyday basis living in a world whereby others are looking at ways to take advantage of what you have while you're trying to maintain the leverage you have and not let them get one over on you. You get to leave the politics of being human behind for a while. It's to have the chance, safely.
