u mean bathtubs instead of a bathtub? i dont know. u cant have sex whether the people are in seperate tubs
Probably because sharing a bath is seen as an intimate object, perhaps starting afresh, on a new journey together, but if they shared a bath, prudes would be freaking out over the message it sent (even though its a sex enhancement drug) and it (the ad) would be pulled (not anything else though)
Why not? It adds that personal' touch.
