Why would you think your attraction to men (or women) would switch off just because you chose someone to be with?
Sexual inclination comes in a wide spectrum :
- some women like only the one male in bed, some like multiple men, some like other woment, some like either sex...so there is a complete spectrum of attractions there
- some women like anal (some don't), some like toys (some don't), some like bondage (some don't), some like pain (some don't)...so there is a complete spectrum there
- some women are exhibitionists, some need a dark room, some like public places, some won't ever consider a camera...none of it is wrong - there is just a spectrum
- some women meet a guy and never really look at another guy, some women marry a guy and can't help but look at all other guys....there's a spectrum of degrees in there.
...you just happen to be at the far end of the spectrum. There's nothing wrong with that - it's just you.
All you really need to do, is work out what you are going to do about it - whether or not you are going to act on it, be faithful, choose a relationship/marriage that is more suited to your sexual drive, or otherwise.
That's the really short version regarding options, considerations (of your husband/partner/kids), and outcomes.
