positive sexuality

I want to change up my sexual routine with my partner. Where do I start?

My boyfriend are "sexually active" but it's always short, boring, and quiet. If I make a sound he'll think that he's hurting me which makes me have to contain everything. I want to try more positions with him, we've done normal, and doggy, how can I make things more interesting with out making it awkward? And how can I make sex longer?...

Deep down I think that sex is bad and wrong. What can I do??

I've recently realized that I have some deep seated negative thoughts about sex. I feel that it's dirty, wrong and I'm bad if I have sex or use sex toys. I've always had some pain when I've had sex but I thought it was because I was nervous that it would hurt, so I would clench and it would cause pain....
