It took some character to get B'Elanna interested in the male genre. Tom had to try repeatedly to keep their relation. He was so strong with his beliefs that they came before serving Starfleet. They kept Harry on the par with women and B'Elanna isn't a lesbian. It was Capt Janeway who saved him and as the seasons advance her trust becomes more fully bonded in him.
Sorry- I can't get out of Explorer 7.
