Praveen, If what you have narrated in the question is true, then you can score if not with all but definitely with few of them. You say they do not resist much to your offensive touch .Some of them including your aunt in fact gives you sort of lift too!
What you lack here in my opinion is self confidence and assertiveness .Women like confident men. So first of all be assured of yourself. Be conffident and when some woman looks into your eyes then try to stare into her eyes to the longest extent . If she keeps staring then give a smile. If she already is smiling then you too should reply with a smile. And instead of trying for each and every woman coming your way, concentrate on few of your choice, Be selective. After this smiling phase get yourself introduced . Do not make any haste at all. Just be friendly and do not reveal your sexual intentions. Be friendly.These women being mature and experienced would take the lead.
@ aunt, when you feel she intentionally is pressing her boobs on your back, you can tell her something is piercing in your back and you are feeling pain . See her reaction. Then start praising her. Not only her beauty but her overall personality, cooking, any skill of her etc. Be her friemd.
Be charming. Wear decent , classic cloths.Use perfume, deoderant . Be polished and well mannered. And this habit of touching women inappropriately is not a nice social behavior. If any woman complains you would be an easy targate of public wrath as well as legal proveedings too!So leave this habit at once .
And as goes with these sort of questions Do remember our disclaimer that only you would be responsible for the consequences of your actions. Best of luck!
