The Best Tips

These have always worked for me
If you want him to put his arm around you the best thing you can do is sit next to him and slightly lean into his arm

If hes shy about touching you move his hands around you or if youre shy too then pick up his hand, look at it, measure it against your own, mention if you want to how much biger and stronger his hands are, and then just slip your fingers between his

if youre beyond that jump on him and tickle him. my boyfriend always ends up grabing my wrists and ending up ontop of me...
