bisexual or greedy??

Ever since I was a little girl and found my stepdads playboys when I was 11, now 22, I have always masturbated to lesbian porn, images of women's bodies, even men's gay porn. I have never dated a woman, but I've always found women to be a very powerful figure and it attracts me to them. I've had a threesome before and loved every second of it, and now I'm currently in a long term relationship with my second daughter's father. I know that things aren't going to work out between us and I'm scared to be single, I want to keep my options open and stay open minded about the love that could come my way but I always get pulled in by the assholes. I feel like I could only invest myself sexually in a relationship with a woman though.. 🤔
