ASD, Sexuality and Relationships

Hi, just wondering if anyone has any experiences of Asperger's / High Functioning Autism, different sexualities and relationship styles? ImI a 37 year old man with Asperger's. For 10 years 've been in a monogamous marriage to a woman. But over the last few years I've come to understand myself as bisexual as I'm attracted to men too. I want to be able to express my attraction to both men and women so I don't know if monogamous marriage is right for me. I feel more drawn to a more open arrangement like an open marriage or other forms of polyamory. I guess I was wondering if my experience has anything to do with being autistic and maybe not understanding the nuances of love and relationships so well, or is it just to do with my sexual identity? If anyone has any experiences or insights here I'd be grateful. Thanks.
