feel like I gotta pee not cum

I was using a dildo to masturbate for the first time and started making it go in and out super fast and it felt good but then it felt like I had to pee, so I went to go pee and then resumed my me time and it still felt like I had to pee when it started to get to back where I was. This has also happened when my man used a vibrator on me I just felt like I had to pee but nothing would come out and the it's just started to feel uncomfortable. He said if it feels like I have to pee then I'm about to cum but it didn't feel like that pent up feeling I get when I orgasm from rubbing my clit. Well I didn't come either way but it didn't even feel like I was about to cum. Is this normal? btw I've never had a vaginal/g spot orgasm ever in my life
