Why is it ok for boys to have their shirts off on facebook?

[Jessica]

My boyfriend is a personal trainer n lately hes been posting videos of himself working out on facebook an its really starting to piss me off. Girls comment on it an like it an shit an im getting sick of it, im like really an hes like this is what i do , an im like ok im jus gona post a video of me working out oan bending over an see how u like it. Why can boys take shirtless photos.an pictures flexing an its ok.but if a girl shows her stomach or to much shest shes a hoee?
Sometime help me with this situation.

don't feel so insecure. no one will grab him away from u due to some fb pics. how old are are you? anyway, never mind.

I don't see it as okay. If he does it with the intentions of showing off it's completely unnecessary and attention calling.
