70's porn, all those kevin keegan perms, tom selleck moustaches (and thats just the women)
Naff clothing (usually again in the 70's porn films)
and I am sorry, but bad taste in decor is a big no no foe me...I hate it if their duvets clash with thw wallpaper, or the cutrains dont go with the carpet.....I spend ages criticising them for bad taste
most other stuff is ok...dont much like watching cum drinking or creampies, but love watching aguy wanking and cumming everywhere.
