Hey 28

Hey all. I'm a 28 year old guy, starting my nofap journey today. I've always been watching porn since I've been 14 or so. I don't mind watching porn too much, maybe I watch a maximum of 1 hour a day and some days not at all. I'm also OK with my sex life, even though I watch porn I still seek out partners. But because of so much masturbation (usually daily) I experience problems in the bedroom. I've become so used to masturbation that I find it difficult to come during sex. As you can imagine this can be quite unsatisfying. Recently I try masturbating with more lube to make masturbation feel more realistic, but frustratingly, even in that case I find it difficult to come. So I hope by giving up masturbation for a period of time might help to resolve this issue. Any advice is appreciated!
