I'm a bisexual (but had mostly heterosexual experience IRL). So, I suppose that I read about GL, BL and hetero romance relationships without even really distinguishing them much? I really usually just don't mind too much a gender of characters.
So I'm not even sure if I could say anything interesting about these aspects.
Unfortunately, in my own comics I have no Girls Love, no Boys Love and no any other Love so far, because the plot haven't driven to such a things yet. Also my comics is just a little above 100 subs, so I'm not a popular creator.
But if you will not find other creators to answer you, I'll try to answer to your interview. Again, I just doubt if I will be able to say anything interesting, so I suggest myself as a backup option, on the off-chance.
