Women fake it. They have been doing it for ages. Various studies have indicated that 70% of women fake orgasms at some point during their sexual lives, according to iVillage.com.

This performance of sorts is usually an attempt to avoid hurting her partner's feelings. For a man, an inability to make a woman orgasm is quite the confidence blow.

As a result of so many women faking it, men have become skeptical. Is she really climaxing? IVillage.com has revealed the tell-tale signs that she really is, in the article, "He'll Know You're Faking Orgasm If..."

Watch for the following signs that your woman is having an orgasm:

1. Retraction of the clitoral head
2. Increased breathing and heart rate
3. Dilated pupils
4. Red lips
5. Vaginal muscle spasms

A woman cannot control any of these orgasm effects, so if she shows any of these signs, she is probably not faking it. Seeing these signs will boost your confidence on your love-making skills and hopefully remove any skepticism. If she is not showing any signs, be secure enough to take constructive criticism.
