Is it normal that i am 19 and a virgin

First, recognize that they are men, not guys.

If you have many men asking you, don't be too choosy, as you probably will not enjoy your first time.

Get it over and done with.

Try to select a male with a smaller penis.
Simply, be up front and personal with him.
Tell him that you are a virgin, and ask him if he will be gentle with you.

Be certain that he has been screened for STDs, and that you are using an effective method of birth control. A condom will then not be necessary or wanted.

In the meantime, practice by imagining you holding and guiding his erect penis into your vagina. (On your back, legs spread open).

On your first experience (and possibly second and third), you might experience some bleeding and / or discomfort. The male might experience some soreness or pain as well.
For it to count, the male must fully penetrate your vagina, and ejaculate inside you.

Three sexual sessions are sometimes required before a female begins to really enjoy sexual intercourse. You might want to select a different male partner for the second and / or third sessions. Be certain that each male understands that you are a 'one finger girl', until after your third session.

If you are successful on your first attempt (no premature ejaculation), and are in too much pain, the male might become erect again, after about 20 - 25 minutes. If you feel that you are in too much discomfort, for him to re-enter you a second time, then you should be fully prepared to ejaculate him manually. In this event, both you and he, should have an understanding where you prefer him to ejaculate.

Communication is essential.

You worry, way to much! The right guy will come along and all will feel right as rain, and it will happen, and your past may just be what he desires!
