Not so much a sex act, per se... it means "deep French kissing'.
If your partner is disease free, yes kissing sex organs is safe.
DFK = Deep French Kiss in the escort world.
When the opposite sex kissing a female on the breast it is called 'foreplay' which means the couple are getting hot and heavy and it could lead to sexual intercourse.
If you get turned on over two people of the same sex kissing it just means that you enjoy that genre of porn. It doesn't say anything about your own sexual orientation.
As far as I know, kissing in movies IS real, if by "real" you mean, the actors are actually kissing each other in front of the cameras. They're only acting; they're not really in love. But they are really kissing. It's the sex that's not real. They don't actually have sex on screen (except in porn movies).
Not because of the sex, but from contact and kissing.
No. Kissing someone is not sex or a type of sex.
Kissing neck or nouge
In contrast to what some people say, 'love and other indoor sports' does not mean sex. It actually can mean anything from making love, making out and sex, to just kissing and touching in a sexual way. So actually, no it doesn't just mean sex.
Kissing!
