I've been having really good sex with this new guy, anal and vaginal and its really good but I don't know if I've had an orgasm.im only 19and I know its stupid but can you still have great sex with out having an orgasm? how can you tel when you have had one

What do you mean by "great sex"?

Like I've had sex with guys who didn't no what they were doing, now this guy does, and it feels really great but the way peopl talk about how hard it is for a woman to get an orgasm and how amazing they feel I'm not quite sure I've had one or not :/

If your not sure about it, then I'm guessing you haven't... talk to him about it, try different things, oral can do wonders, or even different positions can add excitement and hit those spots... The best way forward is to talk to him about it, he won't be offended, to be honest, he will probably take is as a quest... might go in your favour...

Good luck with it anyway :D

You aren't sure if you have had an orgasm?
Answer - no you most certainly haven't.

A lot of people find it difficult and even impossible to orgasm through vaginal penetration alone.

Try using some grinding methods.
One that works great for me is reverse missionary. The girl on top. If you are on top then you can be more in control of the rhythm and speed, you can also grind your clitoris into his hips.

Sorry if that was a bit graphic :)

It is not OK to have sex without satisfaction/orgasm every time.
If you do not know if you have had one then first you must give yourself one.
When you can reach orgasm alone then you'll be able to tell the guy what you need.
Suggestions:
Use a vibrator on your clitoris during intercourse.
Have longer foreplay, get really hot making out and make the guy round the basis making out, breasts, hands in your pants, oral to you and if it gets you turned on you to him and then when you feel like you'll loose you mind if you do not get him inside you then get down to 4th base and use the vibrator on yourself/clitoris.
You'll .

There are vibrators for couples he wears and it makes it better for both.

Also, try a stimulant to your clitoris something to bring the blood flow will make it easier to get off. Peppermint oil,eucalyptus lotion, will really help.

Remember if the guy won't put out the effort to make you stop seeing him.
Sex includes orgasm for the woman at least once a session. Don't settle for less.

You can have good sex without an orgasm but it is better with it.You feel more sated when it is over.

A man would be in pain(blue balls) without an orgasm but a woman just might feel* that was good but is that all there is*?

As has been said if you have had an orgasm,you will have no doubts about it.

I suggest you masturbate and get to know your own body and bring yourself to orgasm so you can better inform your partner how to bring you there.

Since you are new to this please be sure to use caution when having anal sex and vaginal sex as any fecal bacteria in your vagina can cause a bad infection.

Do not ever go from anal to vaginal without changing condoms.
