This is something I have no experience of - and so feel very odd even putting it down in writing - but my sisters new boyfriend is a very nice middle class university educated guy - sorry to put it in those terms - but need to stress - very normal guy. But he is incredibly tactile with my children - to the point it feels creepy. I just came upstairs as he was telling my Dc a bedtime story (sister was also there) and he had his arm around my dd (8) and then knelt over my son (10) to kiss and hug him goodbye - and it almost looked like he was wanking on top of him - he was only tickling him - but it freaked me out. I adore my sister - and so happy she has found this guy - but I cannot shake the feeling there is something odd. He is perfectly normal when not around the children. Does anyone have any experience in knowing whether I should see these as warning signals - or am I being ridiculous?
