Yes I agree too sex can be messy. A towel or wash cloth near by is very handy.
Your body & your partner's body can also produce some weird strange noises. That's freaky too, but needs to be accepted by each person as "normal".
But being messy means that your body is healthy & working properly. It makes sex more enjoyable instead of worrying about lubes etc. Being totally sexually liberated, on an equal plane with your partner with endorphins flooding your body can make you feel.......like a goddess!
