Not able reach O

Anyone else struggle with reaching an orgasm? When I’m alone, I get close but after an hour of close but not quite, I finish with porn. And it makes me feel guilty so I’m trying to stop but it’s the only way I can finish. I’ve been with my man for 6 months now and he’s gotten me to finish once. Sex with him is so good and I love it but the fact that we can go up to 5 rounds a night without me finishing has put a lil strain on our sex lives.

Any suggestions or advice would deeply be appreciated!
