Is this an STD? (pic included)

Ive had these bumps in my vagina for quite a long time but never really thought much of it until recently when I've been experiencing a burning pain during and after sex. i decided to take another look and realised how bad it was and am worried it could be genital warts? I've had the same sex partner for a year now and previous to this only one other and i know my current sex partner has not got genital warts. i don't know if the burning is related as Its a recent thing and I've had these bumps for a while. any help would be much appreciated.

Doesn't look like warts to me - maybe vaginal cysts??, but I'd get checked out if I were you.  If you see a doctor, please let us know what they say.
