I haven't always had a negative view on sex. I was actually pretty non-judgemental about it, open, confident, I embraced my feminine sexuality through clothing  and my behaviour, posture, gesture, the way I walked, spoke, and was very proud, seductive, free. I imagined once I start being sexually active, I will probably get addicted to it etc. But ever since I started being sexually active, it's not as I imagined it to be.  I'm definitely a different person now, considering how differently I think about those stuff now. It's actually shocking, I'm actually different. The fire has been extinguished. Now all of a sudden I have fear of pregnancy (being super careful), fearful of catching STDs, I am timid and embarassed about having sex, I don't want to have sex as much, I don't have confidence, I am not flirtatious and seductive in general. My views about sex has drastically changed. I locked my sexuality. I would be fine not having sex for the rest of my life, that's how I feel. I obviously have a serious problem and I would appreciate your answers and what I need to do to make things a little more enjoyable in bed.
