Golden showers..

I tend to urinate while having sex...I pee before we have sex..but it happens when my SO..goes deep and I feel like I'm going to orgasam my doctor says it's normal and she calls it the golden showers..any tips on how I can stop. ..I get so embarrassed nd it's weird cause only one other person made me do it besides my SO... No one ever made me do this.....at all...but I had strong feelings for him like I do my SO...
