There's a very practical reason for my self induced lower body convulsions...
Bea is considering ways to handle her sexual tension, and she's been to the diary room and spoke to a female Big Brother about it.
When asked if there's anyone she can speak to about it, she said there's Marcus, but she's not going to go about handling it the way he does.
She tells Marcus about her diary room conversation.
And he tells her what he does isn't to handle sexual frustration.
It's so he doesn't do seepage in the bed.
Which leaves Bea wondering, does that really happen to grown men?
