This isn't funny at all and I do expect red thumbs. I'm only asking here because the only other place I know of that I could pose this sort of question would be 4chan but they're all a bunch of neckbeard virgins anyway so their opinion is skewed.
This is just to satisfy my own curiosity (this question is mainly for the ladies btw, guys can answer too if it applies).
Could you please list:
What do you think is more intimate: intercourse or oral sex? Please explain why.
How long would you have to know someone you just met before you were comfortable enough with performing intercourse or oral sex with them?
