Can't Orgasm

Hey I need help! I know it is very common but I am struggling with trying to orgasm. I have been with my boyfriend for a little over a year and never used to worry about it but it's starting to bother me. Sometimes I feel like I get really close but just can't get there because I have the feeling that I kinda have to pee (which I've read means that you are close). Like I'm able to cum but can't orgasm. If you have any tips please let me know because it's starting to make my boyfriend feel like its his fault😞
