My SO has sensory issues, like lube on her hand makes her very disturbed.. but lotion doesn't bother her. Or any type of wet feeling or oil feeling on her face makes her cringe.

Were trying to get pregnant, but panty liners and pads feel cringe to her, she only uses tampons... but also, the feeling of cum leaking like 30 minutes or even later than that also really grosses her out. Like she's basically resorted to just laying down for like 40 minutes, putting a small baby wipe on herself and going straight to the toilet... hoping to avoid anything leaking but A) that routine is really cumbersome and B) its not really working as some still comes out later.

What's a good combination of things or one thing, to catch the after sex cum before it can get down her leg? We've discussed like a small piece of microfiber towel or something but she isn't a fan of the idea of a thick layer of cloth inside her panties.
