I met this guy at the grocery store I work at and he works with me. I'm 17 and he's 18. We started talking a lot and he always comes over to me at the register. He asked me for my number and we've been talking A LOT. He keeps asking to hang out, but I've genuinely been busy. I kinda think he's flirting with me. But, me being a very anxious person, I am nervous about getting into relationships and the physicality that is involved with them. Any thoughts or advice. Really anything will help!
