Strict, strict parents

I'm Leighann. .First off, I want to say that I legit have the best parents in the world. They care soooo much about me and my sister. They worry about us and only want what is best for us. I'm almost 24 by the way. I still live at home. My parents care a lot....they are very strict and always have been. I live at home and still have a curfew at this age, which is unheard of this day in time. When I was 18 and 19, it was cute. Guys thought it was adorable that I still had a curfew at that age and they respected it. At nearly 24, I feel like I shouldn't have one. During the week my curfew is 10:15 and on weekends it is 11:15. If I am with friends, I can stay out a bit later but if with a boyfriend, I have to go by the curfew. Ive had three boyfriends and always had a curfew. Every now and again I will want to stay later with him and will text and ask for an extra few minutes and they will agree. If I am late (even 10 minutes), they will fuss and say I'm very disrespectful. I love them though, and I do respect them. The only times when I've been 10-15 minutes late is when we were having a conversation and I always hate to get up right in the middle of it and say Welp! Gotta go! My boyfriend respects me and my curfew but says he just thinks its odd I still have one. My friends don't have curfews and have all moved out and in with their boyfriends. Sometimes I think about getting my own place so I could make my own rules but feel like I would majorly hurt my family if I did. They would miss me terribly. I would miss them too. Plus, I don't pay rent or anything living with them so it is easier. My boyfriend always asks why I have a curfew which annoys me because I don't really know. He wants to know what they are afraid of happening. I think they think my boyfriend and I might fool around but we could do that any time of the day so I'm not sure? I'm almost 24 and I'm still a virgin. Ive chosen to remain one until I found the right guy. I think I finally have but I'm not completely ready to have sex just yet. My parents know I'm a virgin so I don't know why they would worry about me having sex. If I wanted to, I could've already, and could now. If I get home just ten minutes late, they accuse me of fooling around, when I don't. Sometimes I wish my boyfriend and I could do things besides kissing but I know I will be questioned about once home. I love my parents so much. I could look the world over and not find better ones. I just wish theyd see my side and extend my curfew. I'm not asking to stay out all night...maybe til 12 or 1230. Any suggestions?
