Then he is neither homo or hetero.
It isn't muddying the issue to seek clear terminology.
Sexual orientation has nothing to do with masturbating with a dildo - apples and oranges.
What exactly is sexual orientation? That is a good question with no clear-cut answers. For example - it's not uncommon for adolescents to sexually experiment with the same sex. Does that make them bi or homo if in adulthood they remain hetero?
Wikipedia defines it as follows:
Sexual orientation refers to "an enduring emotional, romantic, sexual, or affectional attraction toward others,"[1] usually conceived of as classifiable according to the sex or gender of the persons whom the individual finds sexually attractive. The most common forms exists along a continuum that ranges from exclusive heterosexuality (being sexually attracted to members of the opposite sex) to exclusive homosexuality (being sexually attracted to members of the same sex) and includes various forms of bisexuality (being sexually attracted to members of either sex).[1]
Most definitions of sexual orientation include a psychological component (such as the direction of an individual's erotic desire) and/or a behavioral component (which focuses on the sex of the individual's sexual partner/s). Some prefer simply to follow an individual's self-definition or identity.
More recently, scholars of sexology, anthropology and history have argued that social categories such as heterosexual and homosexual are not universal. Different societies may consider other criteria to be more significant than sex, including the respective age of the partners, the sexual role played by each partner (such as active or passive), or the social status of the partners.
Sexual identity and sexual behavior are closely related to sexual orientation, but they are distinguished, with identity referring to an individual's conception of themselves, behavior referring to actual sexual acts performed by the individual, and orientation referring to "fantasies, attachments and longings."[2] Individuals may or may not express their sexual orientation in their behaviors.[3] People whose sexual identity does not align with their sexual orientation are sometimes referred to as closeted.
Sexual identity may also be used to describe a person's perception of his or her own sex, rather than sexual orientation. The term sexual preference has a similar meaning to sexual orientation, but is more commonly used outside of scientific circles by people who believe that sexual orientation is, in whole or part, a matter of choice.
