It takes a certain type of mentality to be able to show enthusiasm when your on top of someone that is big, fat, old and generally not phyiscally your type. This is why, as an older guy, I take all the young gun reviews as ymmv, cause I never get the same experience. I like the seduction girls, really do but my experience there is what I get at a typical mainstream: I enjoy them way more then they enjoy me and most of the time it shows in their attitude, facially, eye contact in some way.
Human nature. Just like I canโt get up with certain types. Some girls donโt turn my crank but its also not my job. Thats why I ended up seeing more the asians at the FS azn places and SPs. They have a way higher level of bed side manner for ppl like me
