My 'hot spot' tends to be the penus.
But other than that, if you want to lead up to it instead of going right for it (which would be kinda cool too!), here's what I like.
Massaging my chest. Don't know why, but it makes me feel good and makes me feel like you appreciate my body. Squeezing the butt, definitely, kissing my stomach or nipples (I've concluded that the only reason for male nipples is pleasure), tongue in the ear (I like it, but that's a touchy subject), the scrotum, etc.
Of the above, I like massaging the chest and kissing my stomach and chest the most.
