Level 0 Newbie, Just learning basic social interactions atm.

So I've been going to this local meditation meetup about every once or other week for about a year now just to learn to calm my mind. Some of the regulars bring their kids (infant-grade 4/5?) on occasion and they're pretty comfortable hanging out with me now.

Occasionally though, since kids (boys & girls) aren't afraid to ask, they will ask for a massage (coz they know I was a massage therapist in the past) and its simply just me poking, proding and compressing their backs and muscles for a little bit while they just wiggling around and giggling. No big deal.

However, when they do ask me, and I just indulge the kids w/e. Its very reminiscent of my tendency and past experiences of me being the 'nice guy' and 'white knight'.

Question:

Now I'm not asking how to 'game' the kids. But I would like to know what can I do in this situation to establish a better habit that is more indicative of 'seduction' skills that are transferable towards dating women (investment & win-win principles???, I'm not sure)
