I feel guilty about lying to my boyfriend

when my boyfriend and I first met I didn't think it would go anywhere at all. he has had sex with about five girls and I wanted him to like me so I said I had sex a few times with some different people. but in all honest I was a virgin and I just wanted him to take me seriously since he was about a year older than me. we have been together for 5 months now and he is honestly the love of my life and I just feel guilty that he thinks I have had sex before when he really was my first. it's tearing me apart with guilt but I can't tell him because he's going to be so mad at me for lying.
