Yes.
This is not universally true. Fondling a womans breast when the woman wants you to do so should be pleasurable. Many women are more aroused by the intimacy and passion than by the actual touching.
You don't. Do not be touching anyone's breast that does not want you to. And the fact that you are asking indicates that you are not old enough to be touching breasts.
By pressing girls boobs.. It starts increasing
Because girls like guys with big muscles :)
If you mean touching like touching a buttock or a breast then yes that is lust.Do not do that that is foolish.
yes they do like it when u massage there breast
It probably depends if the person is a hard sleeper or soft and it depends how hard your touching her.
only when they initiate it
That's a definite no.
Bcoz they are enjoyable when touching
he can't
No, it is not. You should touch a breast everyday. By 'cheating' I presume you mean having sexual adventures outside your present relationship. Touching someone else's breast on purpose would certainly indicate that you have an intention to cheat.
Typically you don't see a breast cancer lump, but notice it when touching, washing, or scratching your breast.
