I'm a straight guy and a fan of f/m tickling videos. I enjoy these videos because I am sexually submissive and I like to put myself in the male 'lee's position. I assure you that there are TONS of other guys out there just like me, though many refuse to speak up due to the stigma that exists in our culture against men being something other than dominant in their sexual relationships. Since they won't speak, I will speak for them.
1) Tasha's great, but watching the same female 'ler over and over again does start to get a little dull. I want to see videos with a wider range of female 'lers. Personally, I WANT a 'ler who verbally teases and taunts the guy that she's tickling; this allows her to assert greater psychological control over her victim, and what is tickling about if not a loss of control? Perhaps let multiple female 'lers loose on the same male 'lee.
2) The male 'lee should keep his shorts on, but the female 'lers should also be able to explore his private areas. Nothing is sexier in a tickling video than when a female 'ler, grinning wantonly and mischievously, allows her tickling fingers to breach her victim's waistband or begins tickling his groin over his underpants. Ticklish guys tend to be really ticklish in this area anyway, and to see a woman assert that kind of power over a man by touching him so close to his junk is sort of a double turn-on for f/m tickling fans with my sensibilities.
3) Foot tickling is cool, but upper body tickling is better. Let's face it: male feet aren't particularly attractive. The female foot is slender and dainty and can truly be an object of beauty. Men, well, not so much. It's much more fun to watch the male upper body tickled. Because there are generally more square inches on the male upper body than on the female upper body, and because guys don't have boobs to get in the way, there are a myriad of ticklish patches of skin on the upper body of a male 'lee easily accessible to the fingers of the female 'ler. Plus, female 'lers just seem to enjoy upper body tickling better. They're probably much happier running their hands all over some guy's pecs and abs than his feet. Stretch the guy out and let them go at him.
4) Male 'lees should be ticklish. We've all seen those videos where the guy being tickled doesn't appear to be ticklish at all and is trying to force a laugh while admonishing the female 'ler to "cut it out." There are tons of dudes on this site alone who are super-ticklish and want to be tickled by women. Find really ticklish guys who will screech with the best of them when tickled and leave them at the mercy of a female 'ler or two.
5) Finally, nothing is hotter than when the female 'ler seems to genuinely want the guy she's tickling on a sexual level.
