Some scenes in the workshop require you to have a certain arousal amount. best way I've found to get that up above 50% (the amount you need for all scenes) is to stand in the shower and chainsmoke like a madman. You can make it part of the morning cycle where you cook eggs and steak, stand in the shower while it cooks and smoke (steak takes a long time) and then eat the egg first and steak second. The reason being is the food drain is determined by the last thing you ate and steak is the lowest drain. Now that all of your non-booze bars are up you can go to work so long as it is past 9am and before 6pm. As for the club, the scenes for the upstairs ladies trigger but tossing money at them with x, but it requires a boatload for each scene. The blowjob lady doesn't seem to work but you do need to drink some booze before going downstairs for the prostitutes, get awkwardly close to them until a screen pops up and then you can click the finger in penis symbol to start a scene. These are kind of annoying because you need to rapidly click in the right spot enough times to advance the scene. It's either head, center back, or butt I think.
Other scenes I've triggered at times is if your apartment is dirty enough (no idea what makes it dirty btw) you can call the neighbor with the landline and have her clean. I don't do the dishes one because she barrels through them too fast to do anything fun. Same with cleaning actually but I've found that if you leave a bunch of cash on the floor and start chucking it at her while she cleans she'll sometimes strip and you can repeat the scene you get during a new game. Also at night on the computer you can send money to her stream, enough allows you to go across the street and do the hump bump with her. She wants you to use the phone to stream but that just gets you money and willpower then does a 'level up' screen that causes her to disappear for the night.
