bonds relating to the internuclear axis

Can someone confirm my thought process about this? So sigma bonds have electron density with symmetry around the internuclear axis like a single stick which allows it to rotate, but pi bonds are an addition on the side of the internuclear axis which prevents rotation right? Is it due to the face that the p orbital has more lobes than the s orbital?

I think the way you're thinking of it is fine. I actually think about it in more simpler terms; I just think that if you try to rotate two balls (representing atoms) when they're stuck together by 2 sticks, then the sticks are gonna break, the same way the pi bonds would break.
