You are not alone. Many gay and bisexual guys aren't interested in anal sex. Many feel that they must choose to be top, bottom or verse to participate in mm sex. It doesn't have to be that way.
You need to find a guy who has the same feelings as you. A healthy mm sexual relationship does not require anal sex. Many men find it much more pleasurable to cum together in a 69, a stroking frott, or by rubbing cocks.
Anal sex is not for everyone. As you have tried it and don't find it pleasurable, then don't do it. Being more submissive, doesn't mean you have to submit to something you truly don't enjoy.
Sadly, porn portrays that anal is a necessary part of mm sex. Remember, porn is not real life. What you enjoy is up to you and up to you to find someone with similar desires.
Though I am mainly straight, I have had my bi experiences along the way. I know that receiving is not for me. It is uncomfortable at best and tends to be down right painful. If you try it several times, with care, to the same result, then it isn't for you. I say "anal training" is bullshit. It just trains you to tolerate something you don't like. I don't find giving to a man pleasurable either. It just doesn't feel right. With a guy, I'd much rather cum from oral or cock to cock. I don't mind giving to a woman. They are anatomically different there and it can be pleasurable to me. It's not something I ask for. Being on the large side, I'd usually get refused. Women who like it, ask for it. But, I'd much rather cum in a hot mouth, or wet pussy.
If you have tried anal and don't want to do it, chances are, your body is trying to tell you that it's not for you. Don't feel you you have to do it because you choose a gay/bi lifestyle. Your limits are your own choice. If someone doesn't respect your limits, then you shouldn't be with them.
