Am I being 'humped?'

[ReptiGramma]

I know that you all think that I am a little 'far fetched'---wiggy---looney---odd---even stupid, but I just can't figure out what is going on here.

I thought at first that because my baby Burmese had a mite problem, that she was just scratching her belly on me, but.....I have become a mother to 1.2 CH baby Ball Phythons, and 5.0 CBB baby Ball Pythons last week...The 3 CH babies came from Boca Morphs out of Florida and the 5 CBB babies came from a breeder in the Detroit area.

Anyway, All of them clench their bellies on my hands and arms when I handle them. I wear alot of bracelettes and they act like they are rubbing and clenching their stomaches on them, and then they continue this gyrating movement on my arms and hands.

They don't seem to be acting defensive while doing this. Nor do they seem to be doing it out of stress, or trying to get away from being handled. They do this after they become relaxed and start exploring who is handling them.

What are they doing and what does it mean?

Thanks,
