This was mentioned in the Day 5.5 update devlog on Itch (and further explained on Tumblr), but all original sexual content is now part of the DLC you mentioned. So please visit the DLC page and use the free version if you'd like to have those scenes back.
I also don't have control over which payment methods are available on Itch, so until the PayPal/credit card issue is resolved (or if Itch finds other payment processors), I can't accept or offer any external payment methods. You can read the FAQ to learn more!!
