different ones are given for different STD's
Yes, there isn't one antibiotic that would cure them all.
If you are concerned you have an std, you need to be seen by a doctor (either your own or an std clinic) and be tested.

for now i don't have the courage to see a doctor,aside from that here in the philippines it's very expensive to go to the doctor, especially for that has no work yet.
it depends on what kind of infection you have. If it is bacterial (e.g syphillis) it is cured with antibiotics. But for viral infections such as Herpes and HPV, antibiotics would be a waste of money. Isn't there some kind of clinic you can go to? You can't diagnose and prescript yourself for an std. Some of them look a lot like eachother and others don't have any symptoms at all. Don't take any medications in vain for it can do you more harm than good.
Do you have any symptoms that make you think you have an std?
Aj
itchcy, during intercourse it has an unusual smell, but i not sure.
It sounds like something could be going on, so getting tested is a good idea. You could have bacterial vaginosis, which isn't an std.
Have you talked to your doctor? They might be able to refer you to a free clinic - there are some in the Philipines.
