Yeah, same here. I'm pretty good at masking it though, and often act sociable and talk a lot (I talk a lot when I'm really excited OR really nervous/freaked out), but also notice I sometimes let people walk over me too much and have a too weak spine. I feel like... well... a sissy/spineless dude, kinda.
I also come across as very scattered and weird, cause I think faster than I talk and (especially when nervous and just meeting people) cut off mid sentence (I know it's annoying...) which leaves me flabbing out some random words, lol.
Also, my length is as well a blessing as it's a curse. My face and voice are of a 12/14 yr old boy, while my length is that of a fully grown person or someone in their early teens (aka; you'd expect a more 'mature' face with my body, which easily makes people link that together to "Ah, so it's a woman!" :<), and mostly I just don't pass. If I do I constantly feel like they are joking and are actually seeing 'through' me all the time... stupid mind...
Actually it all boils down to that I'm just too insecure... :/ pfft I hate it...!
