I gave it a try but only got suggestions to search for "hoesje voor samsung galaxy a12" (phone case for Samsung A12), "hulpmiddelen voor bandenreparatie" (tyre repair things) and "horloges mannen horloge luxe merk" (luxury brad male watches) and similar things. I never shopped at Aliexpress so I do not have a search history there, I also wipe cookies and browser-stored data between visits to commercial properties and I refuse all third-party content (31% of the Aliexpress front page is blocked but it still seems to work). Could these lewd suggestions be related to whatever it happens to infer from the visitor's history? It is worth an experiment...
I just set up an unprotected browser (Chrome) in a container and cycled through the nl.aliexpress.com front page about 30 times. It gave me a number of suggestions like the ones mentioned above, none of them of sexual nature. I then closed nl.aliexpress.com and opened pornhub.com and xhamster.com, closed those sites again and opened nl.aliexpress.com again in a new tab. It gave me a suggestion of 'neukende vrouwen' (fucking women) after reloading the site three times. This could be a coincidence, of course.
I don't know, I opened nl.aliexpress.com in a private browser tab and immediately got the NSFW suggestion on first try.
The class of the div where the suggestions are placed is class="hot-words", so I would say this is the result of someone spamming the search box with nasty terms and AliExpress just showing them based on 'popularity'.
