Men help me please?

im brazilizan columbian and black. I attract alot of men but they will stare at me and make comments on my looks but thats it especially white guys it's seems like men just think about when they see me rather than a relationship because of my exotic looks. even once they get into a relationship with me they just wanna have all the time they just wanna be my boyfriend to bone. i'm having trouble with my husband now because he's with me because of my looks. it seems like men cant see past my looks and women think im a slut because i have a big and a nice rack. why is it so hard to find a man
