It is a good question. If you talking about navels and bellies, the answer is probably yes. But, if you talking about bugs and beetles, the answer is certainly no. Many parts os female body atract the male attention. Yes, lips, feets, hands, etc. For ones, the female navels is more attrative then feets, for example. For me, if this interest not involve violence, shame, pain, porn or humilation, is not weird, only admiration for female body. Obviously it is only a cute detail in a woman. I like so much eyes, leg, hair, smile and, more than all, intelligence.
