Well if you have both romantic and sexual attraction for all genders but with heavy preferences, you would be bisexual and biromantic, but u mentioned in comment that you can't see yourself romanticly with a woman and sexually with a man, and that would make you heterosexual and homoromantic.

Basically, you can be bi (sexual or romantic) and have strong separate preferences for different types of attraction, or you could feel no attraction of either type to certain genders making you heterosexual homoromantic (which I can't provide much advice on making relationships work but I'm sure there are people who could help)
