Your arms look great, look like any typical women's arms. I also think, seeing pics of you, you look very much like a pretty woman to me as a whole. I think you're just getting self conscience over little things, which again is typical of most women, I get like that and my mom always tells me that I'm fine, and that if I weren't she'd let me know, and she has at time. I'm always concerned most about my tiny bit of facial hair, I always got a few specks of black stubs just under the surface, but it don't ever give me away as a guy, at least not yet. I think so long as you carry yourself well as a woman, you'll be fine, just have confidence.
