Good sex?

Me and my partner have been trying to find out what works for me so far it’s only fingering and hitting my g spot but even then I haven’t been able to finish. I haven’t really ever enjoyed sex and penetration. It’s not bad I just don’t get anything out of it. I love my boyfriend and I am very attracted to him but there’s a disconnect between foreplay and sex. If anyone understands or has tried anything worth introducing please let me know
