Ladies.. would you consider a picture like this indecent?

i am wearing a thong...so most of my but is hanging out.. and taken from the back....at an agle.. so you can see some of my side but.. maybe 20 degreess.. .. cut of at about where the bra/ bikini top is. so you cant see my shoulders bikini top or hair... .. ? . I pesonally think its sexy ... but is this going to far... i am 35 years old btw and just trying to look sexy for my bf. ... I have no problem with nudity.. but just in case this gets out.......
