Sander Jennings is getting open and honest with his social media followers.\n\nIn a message shared to his Instagram Story on Tuesday, March 15, the reality star candidly expressed one of the struggles he has faced as an LGBTQ advocate and a supporter of his transgender sister Jazz Jennings."I was always supportive of my sister and the rest of the LBGTQ+ community, but often feared the judgment of others," Sander, 24, revealed before opening up about his own struggle with rumors about his sexuality.\n\n"People would continuously question my sexuality for being an activist and bullied me," he wrote in Tuesday's post. "Once I finally looked myself in the mirror and realized that I was so passionate about Allyship because it truly saves lives and recognized that my story as an ally to my transgender sister can relate to so many people."SANDER JENNINGS CLAIMS PEOPLE ARE 'QUICK TO JUDGE' HIM BASED ON SOCIAL MEDIA AFTER REALITY STAR 'TURNED MY DREAMS INTO REALITY'\n\nHe also shared the statistic that "95% of the population doesn't identify as LGBTQ+ and therefore can be allies."\n\n"I started not caring what other people think and started being the activist I was passionate about being," he added in the heartfelt message.In another Instagram Story, Sander later defined his sexuality in response to a fan question, confirming that he identifies as heterosexual.\n\nIn the latest season of his family's hit reality series, I Am Jazz, the digital marketing expert was seen exploring new dating experiences while going on dates with a transgender woman for the first time.SANDER JENNINGS CLAPS BACK AT INTERNET TROLL FOR 'BULLYING' HIS TRANSGENDER SISTER JAZZ: 'IT'S NOT RIGHT'\n\n"I've never dated a trans woman, but I know that I'm only attracted to women, and trans women are women," he said during a previous episode, as OK! learned.Following the episode's airing, Sander took to Instagram to further reflect on the experience, confessing: "Years ago, I didn't feel comfortable even discussing that one of my first kisses was a transwoman."
