First time I tasted my partners cum I got hooked on it

I am a 30f and my bf is 32. We met about a year ago and have been living together for about 6 months. He is everything I have ever wanted in a partner, truly my soulmate. <br><br>We have been swinging for a few months now and I have met a few partners. Everytime I have a new partner I have to give a blowjob, as much I hate it, I do it. Not because my partner wants me to but because I am obsessed with comparing their cum to my bfs. <br><br>I have to do it, otherwise it stresses me out. Everytime, it's more disgusting and bitter than the last. Everytime I have to remind myself that it doesn't matter because I have my bfs cum. I dont know what to do, I really enjoy swinging and exploring my sexuality but at the same time I am obsessed with the thought of my bfs cum, I even preferred tasting it over licking his penis. I dont know what to do, and I really want to stop it. I dont know how much longer I can handle the taste of other mens cum.
