If i remember correctly, there 2 sex scenes in Normal Logan route. First one during 'I own you a beer' event, but if you are having sex with him here, he will hate you. And another one in new update event which you should try once!
Huh? Wait, wait xD, if you choose to have sex with Logan in the "I own you a beer" event you lose 1 heart? Is that what you mean Itsara? if it is, well it sucks then, and now I am not that worried I accidentally skipped this event haha.
