Discomfort During Sex & Fingering

Lilly
I lost my virginity months back and I noticed that the couple of times I had sex with my boyfriend and gotten fingered by him, I always feel uncomfortable and no pleasure at all. Like, no pleasure whatsoever. The fingering has always been discomforting even before I had a boyfriend and I can't seem to find my g-spot. There used to be no pain, but I noticed that after I had sex I seem to be more tight? I'm not sure and I'm really worried because I don't tense up during and I think there's something wrong with me or my body :c
