Never had a boyfriend

I’m 17 and never had a boyfriend. And before you guys jump on me and tell me I should focus on school please just note I’m a straight A student who maintains a 4.1 gpa while also juggling cheer, lacrosse, and work. (IM VERY FOCUSED! Lol) Besides that my romantic life has been lacking. My friends are all bragging about how they’re in amazing relationships and how they’re so in love while I just smile and support them from the sidelines. I’ve never kissed anyone. I got asked on a date one time but he ditched me last minute. I’m worried that maybe there’s nobody out there for me. I just get more depressed about it everyday. I just can’t help but feel in the 17 years I’ve been alive I should have at least kissed someone right?? I’m confident in my looks and personality but I’m starting to think maybe I’m the problem. Even my 15 year old sister has been dating someone for the past 6 months. I’m getting really frustrated and needed to rant. Any advice?
