I don't know anything about STD's so I really can't help you with that. What I can do for you is offer you some advice. Men want a chase, they don't want a woman that will go to bed with them when they want. If you really want to keep a guy around, hold out. You diserve a man who will be with you for you and not because you put out. You need to respect who you are on the inside and outside. You diserve better then what you are letting yourself believe you do. Maybe you need to go talk to a doc and find out why it is you don't feel that you are good enough as a person. Most women that are sexually active like that don't believe they diserve a guy who will stay with them without them putting out. Consider your body a temple, and treat yourself better. I know I'm not your mother or sister, but I am a female and I do know what it is like to feel that unless you put out that the guy won't stay. If a guy won't stay with you because you won't put out, then he isn't worth it. There are men out there that won't leave you. Protect your inner beauty because one day you will find a man that you will spend the rest of your life with, and you both will have children. Some STD'S can be pasted from mother to child, and I know that you don't want that to happen. My advice to you is stay away from men right now and find yourself. Fall in love with you, and you will be surprise how guys find that so sexy in a woman.
