well i mean it can be a little but you just get a towel and wipe it off, just like cleaning your face normally, the tits are more fun though cause you can lift them up and lick them off and sometimes get your partner to get hard again
most of porn is actually fake, from the cock sizes to their lentghs of time, most men are fitted with a pump that the girl has to inflate their "cock" to make it look bigger.
