Hello, Thank you for writing to us, No ejaculation in vagina indicates that she will not be pregnant. If we talk about vomiting sensation and bloated feeling in stomach than it should because she lost her virginity and mostly there are some mentality is there that this problem happen to everyone so we are thinking like that it happens to us also. Paining may occur if amount of pre cum from vagina is less and due to that penis cant enter in vagina easily and due to that it might possible that you had paining issue. and while loosing virginity than its normal nothing to worry. Still if you want to be sure about pregnancy you may go for pregnancy check kit. Pregnancy checking kit is easily available in market and gives you perfect idea about pregnancy. All you have to do is just take sample of your morning pee and test it with the kit it will shows you clear result for pregnancy. For future intercourse i would advice that you may use lubricant if it happens each time you had sex so that penis could enter easily. Or you should use different positions in which penis enters easily. But i would suggest to go for foreplay and Oral sex first before you go for intercourse because it will help for pre cum and also you and your partner will have more pleasure than normal intercourse. Still you are facing the same issue than i would like to suggest to concern a good doctor and check for issue they will suggest you better. Hope you will find it helpful. Thanks & Regards, Dr. Gaurav Prajapati
