I had doctor's appointment and they did check for STDs and I didn't come out with any. But, every time me and my boyfriend have sex, it hurts a lot and I bleed moderately not even when I'm on my period.
Well is he taking the time to get you all wet and ready? And the more relaxed you are, the easier it will be to have him inside you.
If you're just not comfortable enough with him to be having sex, you need to tell him, and he needs to respect that. Don't have sex just to make him happy.
