Im Stress is an erotic cinema in Heilbronn that sets out to be more lounge than traditional porn cinema: the focus is on style and a high standard of hygiene rather than big screens, which it sums up as a swingers' lounge meeting a porn cinema. There are eleven themed booths, some with a massage table, a four-poster bed or BDSM fittings such as a swing, a cage or a St Andrew's cross. Three booths have screens, the others are deliberately screen-free, two are fully private for couples, and there is a central shower.

Soft drinks and coffee are included with entry, and alcohol is sold at the bar. Payment is cash only, and lockers and towels are available against a deposit. Thursday evenings are aimed mainly at bisexual and gay guests, though everyone is welcome, and Fridays are themed nights with changing mottos and sometimes a dress code. The club is open from Wednesday to Sunday, with last entry at 23:00, and is closed on Monday and Tuesday.
