You don't need to be afraid of telling your doctor anything. They are there to help you with any problems you have, and won't judge you for anything. I highly encourage you to see one, at least at a clinic ( Planned Pregnancy if you can get to one, for example ). It's easier if you tell your mother now rather than have her find out later what you're up to. She will probably be upset, but at least let her know that you're trying to be safe - I assume you're using protection, if not then you should be! No excuses, use birth control pills or a condom, and "I don't want to wear a condom" is something only a selfish boy will say. Protect yourself from disease, STDs, STIs, and pregnancy any way you can. And when you're having sex, use lubrication - it can help make it easier on you and him both, especially while using a condom. If it still hurts, try another position. ( I'm not encouraging sex at 16, but it's your choice and I want to help! )

Now about the pain. It's pretty common for endometriosis symptoms to show in your teens, and this sounds about what I went through ( though I didn't have sex until my 20's, I did have a lot of pain during and after sex ). If a tampon is not enough, then you should use a pad or thick pantiliner in addition to it. It sounds like your flow is very heavy, and you should see a doctor about it to see if you can get help. Many forms of birth control can make it lighter and help with the cramps. If you're going through 2 or more in less than an hour though, you need to go to the ER because there could be a very serious bleeding problem.

Endometriosis can only be properly diagnosed with a procedure called a laparoscopy, but there are several other things it could be. Your doctor will want to do blood tests and probably some ultrasounds to see if you have any other issues such as cysts. Your symptoms fit that, but there's quite a few other problems it could be, unfortunately.

You will need to get a pap smear and a vaginal exam too, since you're sexually active. It's very important to make sure that you're healthy down there.

How is your diet? If you're not getting enough water ( or juice, milk, tea ) and enough fiber, that could be causing the constipation. It's not an unusual symptom, but this symptom itself sounds like it might be more gastrointestinal than feminine related. Eating a lot of sugar and fats can cause constipation and other stomach pains. If this happens constantly and your diet is good, then you need to see a gastrointestinal specialist. If your diet is bad, then eat as healthy as you can and get enough liquids ( no soda, alcohol, or coffee ) and enough fiber for 2 weeks, and see if that helps.

Fiber can be found in fruits, vegetables, basically anything grown in or on the ground. It's a very important part of your diet, and most people don't get enough of it. If you need to, get a fiber supplement that you can add to food or water. It's really important that you eat well now so that your body won't have more problems down the road.

Good luck, and be safe!
