I had long wondered if psilocybin mushrooms would enhance an erotic experience.
Yes, they do !

People vary in their dose sensitivity, so the amounts below are  
based on  my experience.

2 g of mushroom is a good dose for a 64 year old man weighing 160 pounds.

If you take too much, you will not be able to maintain an erection.
I think a woman could take a much larger dose (8g) and enjoy the sex even more.  

It seemed like the mushrooms and Vickie were synergistic.
2g is not much of a trip--you barely notice it.
But with Vickie the effect seemed stronger.   And the mushroom made
the erotic experience more intense as well.
Also, the two hours with Vickie seemed more like 4 hours.

It takes about 20 minutes for the first affects to appear.
so you could take the dose at home and drive a short distance.
Do not  drive during the trip!
Be careful if you have a history of schizophrenia, bipolar disorder, or endogenous depression.
Be in a good mood when you start---the mushroom amplifies whatever state you are in.
The mushroom does not impair judgement they way alcohol does,
 but it does intensify emotions---you might make decisions you later regret.
If you take a big dose, you are vulnerable, so you need to be alone or really trust the people  
around you.    Women could possibly use it to manipulate men--at the right dose  it can
create an obsession with beauty.
