My boyfriend and I just started having sex and I missed my period, is that normal?
If you are not using protection, there is a risk of pregnancy but there are other factors that can cause a person to miss a period. 
Some questions to ask yourself are: Is my period normally regular? Could it be late? Am I feeling stressed out about life, school or even the possibility of being pregnant (sometimes stress can cause a delay in menstruation)?
If you are worried about an unplanned pregnancy, it is wise to get a pregnancy test. They are available at any pharmacy or free at our office.
Is it true if a girl doesn’t bleed the first time she isn’t a virgin?
No. Many people believe that if a woman has never had sex before, her hymen will tear the first time. (The hymen is a piece of skin that partially covers the opening to the vagina.) However not all women are born with a hymen, and the hymen can be very thin and stretch out with normal physical activity as a child (riding a bike or a horse, etc.) Some women have a hymen and still don’t bleed the first time they have sex.
Every woman is a bit different. If a woman or girl doesn’t bleed or doesn’t have a hymen it does not mean she has had sex.
Can you get pregnant by masturbating beside each other?
For there to be a risk of pregnancy, pre-come and/or semen need to be on the vulva, in the vagina, or around the anus (because it is mere inches from the vagina). This is a very low risk activity for pregnancy and STIs, if the male partner ejaculates far from his partner’s genitals, and washes his hands and body well afterwards.
If you are going to have sex for the first time and you are scared, what should you do?
Very good question. People should pay attention to how they feel inside and what their bodies are telling them. A bit of nervousness is normal but if you are feeling scared, pressured or find you are not aroused or turned on, then it is likely not the right time yet.
Remember if a person is not feeling comfortable she or he has the right to stop sex at ANY time. Consent means two people (or more) deciding to do the same thing at the same time, in the same way with each other. Any sexual act that is initiated upon someone without consent is illegal.
