My First Ever Sex

It is funny. I am 24 years old and had my first ever sex with my crush/workmate. We are not dating and I think this is just for our sexual cravings. He is my first in everything. I promised myself that I keep my self guarded until I got married because they say that it is the best gift to our future husband - our virginity. But I fall for him and I love him but it is only on my own.
