Long story but I really need advice

So, I’m 17 and I’m bi, right? And I’m also a virgin. I’ve never held hands with someone, kissed someone, or anything. So, naturally, I’m horny as hell and to help this I asked my friend to help me out as a wingman. I ended up talking with this girl, and I’m really really into her, she is super sweet, beautiful, and funny, but she’s very much of a party girl. (Smoking, drinking, drugs occasionally etc.) while I’m pretty goodie-goodie, I don’t really mind, she’s not a virgin and she’s really experienced in the sexy times. She’s a girl who does more open relationships, and has multiple partners. Again, I don’t mind, but I have mixed feelings about engaging in this sort of relationship. I’m worried that it isn’t like me and that I will regret this is in the future. Since I was little I was taught the importance of having a typical closed relationship with someone and it’s hard for me to really allow myself to be in a more sexual relationship rather than an emotional one. Is it a bad decision to lose my v-card like this?
