Abstinence & Celibacy Support Group
The pressures of sex from peers, the media and culture can be overwhelming, but you are in total control of your body and celibacy is a choice that many are making. Find sanctuary with people who are choosing to abstain without fear of judgment.
So I think it's probably making things worse for you.
It's really great that you recognize your weaknesses and that you want to make a change. You can totally do that!! Take it from me, the longer you hold off on jumping into bed with someone, the more clearly you can see the patterns, the more easily you can identify the kind of men that only want sex, the more effectively you can build your self respect back up.
If you don't have a younger sister, just imagine that you do. What would you want for her? How would you want her to behave in these kinds of situations? That love and protection that you may feel toward a sister is exactly what you should be feeling toward yourself.
You are worthy of love and respect. We all are.
