I can sympathize with the body image worries- i'm perfectly comfortable running around naked, but that doesn't mean i'm convinced that i look sexy, especially after all the things that mess up the carefully prepared appearance!
Personally, my biggest issue is letting him find his way. He is exploring his dominant side, and i think he enjoys it (especially the part where he can tell me to make videos etc) But i have to bite my tongue from saying 'no you're not doing it right!' sometimes. It doesn't help that i'm bossy (in general) when i'm not eager to submit and do whatever makes him happy.
(an example, yesterday i failed to do one of my tasks, and i was genuinely disappointed in myself, but his response wasnt what *i* wanted, and what to me didnt seem like much of a punishment (a mild admonishment and a threat of punishment when he sees me - a month from now) made me less eager to do as i'm told...)
