I haven't got a wealth of experience (variety that is) but I can't resist answering this!
1. More is defintely better - though the first time my lover came in my mouth, I wasn't quite expecting what I got and choked! Still, over my tits and face (which I love) you really can't have too much - can you?
2. Not disappointed - because if he shoots, I've got what I wanted - but as above, more is nice!
3. Thicker yes, but not lumpy. If he doesn't cum for a few days, it can get quite "solid" and I like it to spread.
4. Shooting, definitely - but I haven't had enough to comment on the average. I like it to spray/shoot at me, and I like it hot.
5. Again, no great experience but my lover usually shoots 3 or 4 good spurts, then I squeeze the rest out.
6. I real life or in porn? There's an amazing video on xhamster with Essex Kim and a 21 yo guy. I'd change place with her in a blink!
7. Fantasy? Till I say stop!! Enough to cover whatever I'm pointing him at.
