I'm a male and I didn't feel anything during sex. ?

Last night I lost my virginity to my girlfriend who also was a virgin. We've done plenty of stuff before but that day we were going to have sex. We had plenty of foreplay to lead up to it. But when I went inside her I felt absolutely nothing. We tried different positions and I somewhat felt something when we did doggie. We also used a condom and I masturbate a little more than average and I'm sure those contribute to it. Any help or suggestions would be greatly appreciated!
