What's the most accurate translation for "copping a feel"? Absolutely the best first question I've ever asked on any site, ever.

I've considered:


吃豆腐 (but I don't think this is limited to physical actions)
偷偷亂摸
猴子偷桃 (but I think this is too specific?)


Is there a colloquial phrase or saying that approaches the English meaning and feel?
I would like to use 动手动脚 for 'cop a feel', or 'paw someone'.

他一接近女人就忍不住动手动脚. He can't be near a woman without pawing her.

揩油 and 吃豆腐 are also good options for 'cop a feel'.
