Islamic extremists and female bodies -Somalia

It seems to me that if Islamic extremists prohit the use of women's bras to ensure that their breasts jiggle naturally, they should likewise prohibit men's underwear to ensure that their private parts also jiggle naturally. Jiggling of male private parts should be compulsory and any male found to have an erection in public should be subject to the severest penalties and cut off from the rest of society.
