LOL nice discussion. I consider oral to be either just foreplay before sex, apart of having sex, not the act "sex" but part of the...moment of "sex" I guess. Unles it's just quick i like to give lots of foreplay befor getting to penetration. Or could just be, watching TV and u fancy giving other person some loving and go down on them. I love giving oral (to girls, im a stright male) so I try and do it all the time, my gf says I'm REALLY weird, and I always say "yeah and your complaining" of course that's a no, maybe it is weird but ahh well sod it.
I wouldn't conisder massages to be sex, I consider sex to be sex, but I wouldn't do it to someone if I had a gf, its a bit "too" close. But me and my gf consider even dancing with someone, apart from stupid with your mate or same sex mates dancing, cheating like grinding dancing, so I can understand.
If I wasn't with her though I wouldnt consider anything but, well sexual things as sex
