Advice please 🥺

Okay so I’m 16 and I’ve been on and off with this guy for about a year, the furthest we got was kissing, we’ve talked about doing it but quickly dismissed it, he’s known for having done it with many girl and if we do it, it would be my first, I know I’m ready I feel ready and I’ve talked about it with many of friends. I want to do it with him but I’m nervous to lose it to him since he’s known to have done it with many. Advice? 🥺❤️
