kissing?

was watching shakespeare in love, and the girl and shakespeare were kissing each other several times...
somehow, it looks strange to me... kissing... kissing?
what's the meaning in that?
it's not sweet, nor tastey, nor productive;
it's a physical contact of 2 holes of 2 humans, specified for ingestion... a contact of a bunch of teeth and a tongue and a possible exchange of saliva.

'what on earth is so romantic about this contact?'
suddenly, i failed to comphrehend.

i am either deprived of human contact and have lost a certain sense,
or i have come into a periodic awakening from the romantic trend.
or maybe both.

but really, kissing? YUCK.
