A girl feels "harassed" if you haven't built enough connection and/or she doesn't find you sexy.
A girl also feels "harassed" if she has slotted you in a certain category: friend, potential boyfriend/husband, nice guy. Therefore, she has certain expectations, and if you touch her sexually, you're not living up to those expectations/role.
I think this is bound to happen when you're a beginner and trying to improve your sexual touch and general sexiness. You haven't built up enough experience to read a girl's invitations yet.
There's some obvious things as well. If you just met a girl and have only talked about platonic things, it would be really off-putting to just suddenly grab her ass or breasts. That's most likely sexual assault.
This is a work in progress, so it's my 1st draft of the progression for day game:
Acceptable things for a....
Complete stranger:
- Touch on the shoulder (to ask a question or as an "excuse me" to get through or get attention)
- Touch on the elbow that intermediate/advanced guys use to pre-open, instead of shoulder
- Brief touch on the hand that advanced guys use to pre-open (e.g., there's a FR where a guy touches a girl's hand in a tray of CDs)
Stranger that has just opened ("Hi, my name is Pinot."):
- *Same as above*
- Shake hands
- Touch/hold hand to look at a ring and/or other item (after asking)
- Touch clothing to talk about it
Stranger that has been introduced by a mutual friend:
- *Same as above*
- Kiss cheeks (European-style introduction)
Known guy that has only talked Platonically or is in the "friend" category:
- *Same as above*
- Hug
- Link arms to lead somewhere
- Hand on top of back or shoulders (not arm around)
- If friends for a long time, can cuddle, hold hands, and kiss on the forehead (maybe also massage feet? or should I put that below?)
Known guy that has talked more sexually ("lover") or talked more meaningfully/compatible ("boyfriend/provider") and the girl has given good responses
- *Same as above*
- Hand on lower back to lead somewhere
- Closer proximity of bodies
- Touch hair to comment on it
- If sitting, slight incidental touches of thighs
- If good responses and/or on a "date," can cuddle, kiss on the cheek/lips, hold hands, and touch ears/cheeks
- If very good responses, make out (need to be in a seduction location)
"Lover" guy (she finds sexy and desires him):
- *Same as above*
- Make out while also caressing any part of her body
- Cuddle naked
- Sex
EDIT: This reminds me of the old baseball analogies: getting up to bat, 1st base, 2nd base, 3rd base, home plate.
