I'm a gay man and dating a bisexual man. I haven't had the best track record when it comes to being with bisexual men and it always involves me getting my heartbroken. My current boyfriend is actually really sweet so far and super understanding and makes me feel comfortable. But I had a bad experience in the past with an ex that's sort of giving me PTSD to open up sexually to my boyfriend and scaring me. I'm scared that we'll have sex and he'll leave me because it just doesn't feel the same or as good as sex would feel with a woman and It's making me sad and insecure. I did express this to him before and he reassured me that he wouldn't do something like that to me and that he would want me to feel comfortable and good about myself when it comes to stuff like that. It made me feel a little better but I'm still honestly really scared and upset that I keep overthinking it. :(
