The answer is very confusing. however my perception is that a girl need a moral and emotional support. If i talk about sex my suggestion is not to commence with straight sex, first have to do foreplay which a girl like the most. Giving her pleasure by moving hand on the body and doing love bytes enhance the thrist to reach the climax.
Hug from back side is the best part of this while kising on the back and neck then, reach gradually on the lips. Give her long lip kiss holding hand in hand. After that , a guy can do whatever he want, can remove clothes slowly and can start sex.
