Your sexual sweet spot.

[MichBoyBlake]

My theory is that a lot of guys will show you what they like done to them by what they try to do to turn you on. For example, a guy whose nipples are hotwired tends to assume his partner will like the same and at least try that out. No response, try the next thing. That theory has worked well for me.

 

haha I definitely do this, although purposefully. I think it's a good trick.
