Intro:
We all have seen a couple who are so in love they have lengthy kisses in public, always display affection, call each other cute names and wherever they go or sit, they always appear to cuddle. Many people find that gross and awkward to look at.
My situation:
I really don't mind it when I see random couples who do that on the metro, in the park, when I'm shopping etc. I know I probably won't see them ever again.
Everything becomes more delicate if it is a transsexual couple (a guy and a girl, both trans) you live with, or see regularly otherwise. Every time I am around this particular couple I feel really abashed. They clearly don't mind the whole family seeing them cuddle in the common areas, using romantic talk and nicknames, blowing kisses at each other, sitting in one another's lap in the living room etc. But for me it feels like I am always intruding on their privacy.
I don't want to just avoid them completely. In fact I'd love to have normal conversations with both of them, but they just would not stop being preoccupied with each other. It always feels like they are in a bubble and nothing else concerns them. It is also nearly impossible to have a one on one conversation with either of them since they are barely ever apart. For example if I am having some small-talk in the kitchen with the guy while he is making hot chocolate, the girl will soon come into the kitchen and interrupt our conversation by saying "how is the hot chocolate coming along sweetie", a goofy face, and immediately snuggling up to the guy's side.
The couple in question have previously deflected subtle remarks on their behaviour as "being mean". They take offence quite easily. I get this attitude from them that unless you identify as one of LGBT+ then you can't have a say in what they do in public.
This has been going on for a long while, and I thought this behaviour would slowly subside over time, but it didn't. They appear to be completely oblivious to the fact people feel really awkward because of their gushy behaviour (and yes others in the house have similar remarks).
The question:
I want to discuss this issue with them, but I have no idea how start. I don't know how to phrase myself without coming across transphobic, or mean. I'd like to know if any of you know a good way of starting such a conversation & communicating my thoughts clearly and politely and respectfully.
