In the first place if you are at or above the age of consent it is really none of anyone's business except for you spouse or significant other. If you were in a heterosexual relationship with someone of the same race as you you aren't likely to go home and "Hi daddy, I got fucked last night". So there is no reason to go into any detail about bi, gay, lesbian or IR relationship. It just isn't anybodies business. If you spouse or significant other can't or won't meet your physical needs I don't see an issue with DISCREETLY satisfying your needs.
