New Year Sailing

My new girlfriend is more than a year and has slept with a lot of guys, but iv only had one sexual partner?
I have 18 years and have had only one sexual partner in my life. I recently moved out and live in a new city in my new job. I met my new girlfriend and we hit it off right away. iv never felt so comfortable and impressive about another person before. It is completely crazy about me and we have gotten quite serious in recent weeks. We managed to get on the subject of previous experience and that is a bit embarrassed by his past. She has had over 20 partners and is only a year older than me then. He claims (and I believe her) that was allways safe. (We're sure). But this number surprised and frightened me. my one on his 20 +. I wonder if this will be a problem? I feel I wont be up to your standards, or she might get bored and move on. Does anyone have an idea about the situation? Would you could do somthing to help that are booming? Lke this girl really do not want to be a problem
Everyone has a past. Maybe she wants to settle down and have a relationship you serious!
