Ravali, you have posted several times since yesterday about things that seem to be related to one or two incidents pertaining to you having sex (against you will the first time?, being left by your boyfriend) and now you are asking how to control your feelings about sex. Have I got this correct?
What are you really asking about? Are you asking if you can be an independent lady, have a career and also have sex without feeling guilty? Or, are you asking how you can control your feeling about your boyfriend and how you feel about him? I'm finding it hard to figure out what type of advise you are looking for. Can you help us out a little bit more here, then we may be able to help you sort things out.
