DH doesn't play computer games. However, if he was fat, sweaty, hairy, smelly, stuffing himself with crisps, wearing grubby tracksuit bottoms and stained T-shirts and never shifting from the sofa, I would find that unattractive. Nothing to do with computer games.
I can't imagine he would feel overly attracted to me either if that was what I did.
Smelly, unclean people are not attractive - bad breath, rotten teeth, unwashed hair, smelly feet, dirty clothes - all awful.
But so are other things - unkindness to other people or animals is awful, meanness of spirit, violence and controlling of others, snobbery, not caring about the environment, lack of generosity materially, dishonesty, no sense of humour, nor caring, selfishness, arrogance, are all horrible characteristics (much worse than playing a computer game).
