no it doesn't change after losing virginity, but change with age, it's not the same when you're a teen, young adult or adult.

Thats right, it doesnt change after losing your virginity. Often with age and other contributing factors such as oral contraceptive use, your cycle may tend to become shorter in duration and even lighter. If you find that your cycle runs longer than 7 days, and is fairly heavy throughout the first 4-5 days, then perhaps you should consult a medical professional.
