I started master bating when I was around the age of 12. I began to watch porn before that, just because it interested me. Now that I'm much older, and am sexually active, I've found I can only orgasm when I'm rubbing my clit myself. Whenever I'm engaging in sexual activity with my S/O, I never orgasm. I'm wondering if this is because I tainted myself by becoming too experienced at a young age? Maybe I only get that turned on by watching porn and being alone? I love having sex, and I feel amazing during it... I just can't finish. Thoughts? Help please
