Is IT MY RIGHT too not fall in love or is it out of my control??????????/?

I try not to notice girls who are interested in me even ones i find attractive.. because i have plans for the future and a woman would not fit in it right now... im 20.. but im thinking if i dont have kids someday that im also stopping thousands of other lives from being born.. like its my seed and its my blood line.... but i dont want to get married and have kids.. i want ot travel the world and be an airline pilot../ hiker/ explorer/
