If the feeling is right... have sex on the first date! HERE IS WHY:
1. You'll know if there is physical chemistry
Sure everyone is nervous their first time with someone new, but it is quite easy to tell whether your partner knows what they are doing and wants to please you. People can spend weeks and months dating- only to find out that they are not compatible in bed once they do sleep together.
2. A lasting impression
If the date is good and there is passionate sexual attraction, AKA "fireworks" under the sheets, then your date will certainly remember you in a good way. Endorphins or the "feel good" hormones are released and you will get him/her thinking about you all week long!
3. Doesn't make you "easy"
Just because the feeling is right and you decide to sleep with the person that you like, this doesn't make you promiscuous. In the day and age of moving things "fast", "fast food", no time for dating, work work work- progressing a physical relationship should be based on a couple's decision and not societal standards.
