One (old fashioned) family member expressed surprise until another family member pointed out that guess what, he would actually use a kitchen when he was grown up!
Not only do adults of both sexes use kitchen, and cleaning etc, equipment but a preference in childhood play has no bearing on adult preference.
My son grew up with a toy kitchen, his older sister had it before he was born. She loved it. He never showed the slightest interest.
As an adult my son loves to cook, my daughter lives off take aways, ready meals and begging me to batch cook stuff for her freezer.
Neither of them is homosexual. Their toy preferences did not indicate their adult ones.
Parents who read every behaviour in small children as some sort of indication of adult sexuality do enormous damage.
