My problem iswhen ever I perform sex with my girl friend I don't feel that she got satisfied!
Even my size is 6.2 inchs, and our core sex duration were 8 minutes!
I don't know how I know that she is getting orgasm or may in porn stars they act too much

Plzzzz help me out

Do you ask her if she was satisfied? Are you getting pleny of foreplay time in? Also, you should never try to compare personal sexual experiences with pornography, pornography is entertainment- not a guide to sex.

Ask her.if you both are comfortable enough to have sex with each other and it has been a lasting relationship ask her what she likes and doesn't like.ask her to guide you.communicate

The size of your penis is not terribly important. The length of time you spend on foreplay and during actual intercourse is.

Pornography is... a lie.

If you're old enough to wonder if she enjoyed sex, you're old enough to talk to her about sex. Most girls do not enjoy it until they show their guy what feels good to them. A penis going in and out makes a guy orgasm. So, you're enjoying it. Too bad a vagina isn't an inside-out penis, but it just isn't.

Learn about what works from reading. There are many excellent books available. An older experienced man may be willing to talk to you about his skills and experiences.
