Have them be two dudes or girls that are traditionally masculine or feminine and they just kiss and go on dates.
Basically don't have them be total faggots who lack any sense of masculinity or femininity
Homosexuals shouldn't be so insecure as to act like the gender they are sexually repulsed by, otherwise it confuses them and the bulk of the people around them.
Humans will naturally grow accustomed to what is "different" the more normal it is. Emulate the norm, and you gain eventual acceptance. Do this, and you can now do whatever.
