I don't know why i think the way i do?

i personally think i'm pretty cool i'm 17 rodeo and i believe that i'm attractive. why is it that i feel i in a way need to degrade mysefl in order to be cool when already i have respect. guys respect me and care for me becasue i'm not a sluut and they told me that they think that that is really cool. but why do i feel the need to "lie" about instances about drinking and boys.. i feel like without lying that people will think i'm weird. and also it doesnt help that i feel like my parents think i'm lame for not having lots of boyfriends
