Is this an orgasm?

It sounds like you are getting close but I don't think you are getting there. When having an orgasm the muscles inside your vagina and uterus contract rhythmically which feels really great. There are two types of orgasm. One is a clitoral orgasm and the other is a vaginal orgasm, and these often happen together. Stimulating inside your vagina at the same time you are stimulating your clitoris will help you get there. Especially stimulating your "G" spot, which is just inside your vagina on your front side just beneath your pubic bone. It is located about 1 inch inside and about the size of a large quarter, but a little longer from front to back. Every woman is different about what feels good and what works best for them and also, a lot of it has to do with your state of mind. Being relaxed, comfortable, not worried or anxious helps a lot. Also, by stimulating the G spot, it creates natural a lubricant inside your vagina and makes it wet in preparation for sex. I learned a lot of this from experimenting with my wife when she was still new to sex. Just keep on trying...It's natural and it's good to know how your body works. Especially for you to being satisfied in a relationship/marriage.

I have that too. Sometimes I just can't get there. Yes you need to relax to have an orgasm but I find that you need to tense if you want to "hold it" once you get there.
