One of my friends thinks im a ?

Im uming its because ive never had a legit boyfriend, ive explained though that im just not the type of girl who settles down, i like the chase and thats it. Ive always just believed its because i havnt found the right guy yet and although i am 16 i feel like i still have plenty of time and just enjoy myself and not worry about relationships if im not into them at the moment. The thing is most of my friends have boyfriends or have been in a relationship at one point and me being the only one who hasnt i guess can seem fishy. But to ume im a ? i dont want my friends thinking that. That would defianately turn guys away as well and i might never meet the right guy, but my friend knows i like guys, because i do flirt and hookup with them, and i have dated just never gotten to the relationship aspect. She staright up asked me when we were walking, "are you a " i was teken so off guard i responded quick, so now i dont think she even believes me. If she thinks this others might too? i know i shouldnt care about what others think, but this is kind of a big deal. This is who i am. Im kind of feeling pressured now to just settle with anyone just to prove im straight? what do i do?
