Growing up with porn, straight and lesbian, I went from enjoying the site of men and owmen enjoying each other to wanting to try it with a guy. Have had more gay lovers than women but never cum with another guy. I enjoy the sex, but it doesn't get me off like I do with women. I identify as bisexual (for those who need labels, I prefer simply 'sexual') but to me gay sex is just fun. Relationships proper are with women.
I wouldn't think having gay fantasies is anything that needs to be stopped. And indeed it's probably impossible since we can't control our thoughts. Example: don't think of a white elephant.
We can't not think of something until we think of it. Just one of those weird things.
The more you try to suppress gay imagery and thoughts or fantasies, the more they'll be in your mind. Instead, try to simply see it as something you tried, but didn't enjoy, but is a part of your sexuality.Like any straight-sex act you tried but don't care for. Just because you may not enjoy analingus doesn't mean you're going to stop having sex with women.
