Christ...this message is a tad late.
Isn't it sad that the largest thread on a student forum is about going down on people and not on quadratic equations?
Anyway, I dont think there is any problem with kissing after oral.
Funnily enough, last night at a party, I was licking out my ex-girlfriend (funny how we always end up back together) and just after she came, she pulled me up to her mouth and we pashed violently while we squeezed each other to death...it was amazing.
Then she gave me head (we had no condoms...poor, poor, virgin me..always forgets the condom) and after I came, she pashed me...and I came down her throat...it was a bit gross at first, but I was too Vodka'ed out to really give a stuff...it was all about the intimacy.
I think whatever comes naturally should just be the case...forget ur ideals and just go for it. People are so hung up with right and wrong that they turn sex into a chore. Kisses shouldn't be structured, they should flow...I'm sick to death of girls that are stiff, structured and work like they are reading an operators manual...for god sake, MAKE IT UP AS YOU GO ALONG!
No wonder I always end up hooking up with my ex.
