Strange, almost sexualised behaviour in 3yo since starting nursery

[isthisodd]

I'm not really sure how to explain this, but I have a really uncomfortable feeling about it.

DS stared preschool a fortnight ago and over the last week his behaviour has changed. At bedtime instead of cuddling in bed whilst we read a story he insists that he holds mine/DH's hand with fingers entwined and then repeatedly kisses our hands and lips.

At bathtime he's been touching DD's chest and saying 'boobs' she's 1 1/2 so doesn't have any obviously.

He's also being playing with himself a lot which he hasn't really done before.

I know this could just be innocent, I am loathe to 'sexualise' behaviour and he's bound to act a little strangely having being thrown into an environment with different children, but I just feel a bit odd about it.

What do you think please?

aren't all young children fascinated by bodies - their own and others?

i don't think there is anything sexual about what you describe

DS is a lip kisser and hand holder

My ds is 3 and he asked to kiss me on the lips when I left him at playschool today, not so weird to me. He also likes to hold hands.
Kids learn a lot through roleplay games with other kids and through watching family. Now I a pregnant he is noticing that I am changing too and he asks questions.
Normal behaviour imo.

Entirely age appropriate!

p.s i did say no!

Absolutley normal I would say. All 3 year old boys play with their willy's and continue to do so right up until they are about 20 and even at 7 when they are maybe bored of playing with it, they flash it at every opportunity and think its hilarious.

20! It is also very strong societal pressure and nagging from wives/partners that stops most men permentantly having a little scratch/just adjusting things!

Ok 20 was optimistic....I didn't want to scare the OP...is maybe 40 more realistic? I dont have much experience of it past age 30, going off Ex-H.
