Yes. It is normal.
I should think that *customary* would be a better choice of words. A Marine pal of mine was a bit less certain how to act when his fifteen-year-old daughter was given one of the Japanese vibrator/alarm clocks as a birthday present by a Japanese friend of about her same age, but the present was offered with the sincerest of best wishes and without innuendo or the slightest shame or guilt to it. It was simply a thoughtful present from a girl who learned that her American friend lacked something fairly common among her other friends' personal possessions, and who had done something about it.
