anyone ever felt this way? advice?

Sometimes I wish that I lost my virginity with my ex boyfriend. We were together for a year and a half and at the time I wasn't comfortable doing it and we did sexual things but that's all we really had. The relationship wasn't really good at all, the guy was insecure and pretty overprotective and lied about things to make himself look better. But now people are talking about losing their virginity and it's getting to me a bit. Any advice??
