PLEASE READ/HELP - Does it matter if he's a virgin or not?

I'm 14, 15 in a month. Don't completely blindside all I am saying just due to my age, please. Myself and most of those around me often forget I am the age I am, because I've always been mature for my age, and happen to look a little older too. I've experienced very much compared to others my age when it comes to life in general, such as sometimes debilitating mental illness, all that fun stuff since I was in 6th or 7th grade
I started dating a boy over a month ago, and fell in love. I'm a freshman, he's a junior, and he turned 17 in the beginning of April. He's my first relationship, and was my first kiss and all that. He is a really smart, sweet, genuine person, and not pushy whatsoever, he respects me and my voiced demisexuality and difficulty trusting and all that very very much. It feels like we've been dating much longer than we have when it comes to the comfort and openness in our relationship, 'I love you's (he said it first), I've met his parents and he's met mine countless times, and our parents have met. 
So he was dating this girl who is currently a senior, for a year and three months, and she broke up with him back in January. The relationship was very mentally and emotionally toxic to him, as well. Because of that relationship specifically, I often wonder how far he has gone… and if he is a virgin. I know this is quite ahead of where we are in current, but he is clearly much more experienced than me to begin with, and has taught me all I know. He isn't like some less experienced guys in the sense that it can take a little bit more for him to get hard, as opposed to what I've heard about your average high school boy. 
I was wondering if this should matter to me? I feel as if I may feel a little more vulnerable and a little less special if it turns out he isn't, but that can simply be talked about and worked out, but I know he loves me regardless. Any advice? Thank you.
