default if there is one but usually daddy if there isn't. if the mc is younger i give him a random generic men's name. for a female mc i use the default if there is one, or i call her baby. the first porn game i ever played was dating my daughter and i haven't been arsed to change my naming conventions since then.
depends on games tbh with story driven I usually keep the default mainly for parody games but for most i usually just use an Alias i use for most games
Self-insert, every time. I don't watch porn and only play games because watching another man fuck an object of my desire is basically getting microcucked.
