Help IDing movie: middle ages England comedy

So I remember very little about this movie, which is why I'm having so much trouble finding it. I'm pretty sure it was an awful movie, really cheesy and silly and completely ridiculous.

I think it was set around the middle ages or medieval times in England. 

There was a teenage boy on some kind of adventure, possibly to have sex with a girl.

The one scene I remember is the main character hallucinating some flying penis's with little cherub like wings.

I can't remember who the actual main actor is, but for some reason he reminds me of Ryan cartwright. But I've checked his credits and it's not there.

I think it was likely released early 00s.

The only other thing I remember is that it might have something to do with pie or pi, but I have no idea why.

Sorry it's so vague! If anyone gets this I'll be amazed!
