What Joe said is quite right. You should get tested for diabetes as boils in the crotch area can be a symptom. You can actually have diabetes for a very long time without knowing it.
I have a relative with diabetes who has the same problem and gets boils in that area quite a lot. I myself am diabetic and I dread this ever happening to me.
Best to be tested and find out you aren't diabetic than to do nothing if you are. While you are at the doc's you can get him/her to check out the boils. They will be able to tell you if they are caused by infected hair follicles as Goodsoulette suggested (probably the most common cause of boils) or if there is some other cause. They will also be able to lance them for you properly and/or prescribe antibiotics.
Please don't squeeze them or try to get rid of them yourself. If you burst the sac underneath the skin, which is easily done, the pus can enter your blood stream. It is also awkward and extremely painful to do it yourself. They will, of course, rupture of their own accord if left, but there's no brownie points for suffering the pain and discomfort in the meantime.
Whichever way you look at it though, your best option is to see your doctor about the boils lancing them is the quickest, easiest and least painful way of dealing with them.
I truly wish you better soon.
