Adeel,
You never kiss a woman unless you are sure she wants to be kissed. Men don't like it when women say no so they usually do a few tests before they ask for a kiss.
When you are talking to her - touch her arm. Does she pull away or does she let you touch her arm?
If she doesn't pull away - touch her hand.
If she doesn't pull her hand away - hold it.
While holding her hand - put your hand on her knee. OR Put your arm around her.
If she still doesn't pull away. Ask if you can kiss her.
You can do it simply - Can I kiss you?
Or you can do it in a romantic way - I can not live another second unless I kiss you.
Or you can do it in a more demanding way - I must kiss you now.
If you don't know how to get a woman to know you want to kiss her - you are not ready for a more powerful penis. My guess is that your penis will do just fine exactly the way it is.
