Please help I need advice!!

I'm confident and sure I want to loose my viginity to a great guy. He's also a virgin and is a year older than me (I'm 14 he's 15). The only thing I'm worried about is I'm scared I'll regret it when I meet my husband. I'm scared I'll feel dirty and gross and impure afterwards. I don't want to feel like a slut afterwards. Is it as much of a big deal as people make it seem? Any advice?
