Is being asexual a bad thing? I feel as if I do not have any sexual desires. I would marry but I wouldn't want to do those things, I personally would want to have fun and basically nonsexual things with my spouse.
Marriage and sexual activity are optional rather than compulsory in Islam. If you let your future spouse know that you are not interested in sexual activity and if they are fine with that then there is no issue with it from an Islamic perspective.
