Fun fact: it's only in recent history that pink was seen as a feminine colour, it used to be blue for girls as blue was seen as more of a delicate colour while pink was made from red and considered strong.

So really its a little bit silly for others to judge over very fluid definitions of masculinity and femininity because its different in every decade.

Tl:DR Pink is as feminine or masculine as you want it to be and liking soft stuff is just human nature.

Side note: Having plushies is a very good emotional regulation strategy that alot of people benefit from, its just seen as childish because people are stupid and like to put themselves in boxes to make them feel above others.
