[ Rugby ] Open Question : What position would most suit me in Rugby?

Im 16 Im 6'1 and I weigh about 95kg. Although I weigh that much Im not fat but I am unfit and I dont eenjoy exercising (other than actually playing a sport). Im not very fast but I am strong for my age. I am currently playing u-19s (think it will be 20s soon) and am well able to meet the physical demands. Im asking this because I am currently being played in any position that that were missing (hooker, second row, no.8, open and blindside flanker and wing) but I want to focus on a single position. Thanks in advance :)
