insecurity, sex appeal & sexual tension

i feel insecure not only about my body but about myself. i’m not as confident as i want or should be. with that being said, when my boyfriend looks or even gets into close proximity with another female, i can tell that there’s an energy there. you know that feeling that a stranger gives you when there’s sexual tension? well i can tell because he does this thing where he rubs the back of his neck or plays with his hair & looks down. it’s annoying because i can feel it too and it makes me very uncomfortable.

he talk about other girls like in our class or even about a girl that passed him up in the store. just the fact that he gives these strangers his tone focus and energy frustrates me. he could talk about anything else in the world but yet you chose to speak on these other females!

the most annoying thing ever is when he does this double take of some girl then looks at me either to see if i caught him or to even compare.. i hate that shit. i hate it more so due to the fact that he denies that he does it!

i’ve spoken to him multiple times about how uncomfortable that makes me and yet it still occurs. it occurs so often that i even begin to compare myself to other girls, questioning if they are more attractive than I?

i need some help on how to progress.
