You’re concerned that your penis is short, and that since it sometimes slips out during intercourse, you may not be satisfying your wife. The good news for you is that most women--about 70 percent--can’t achieve orgasm only with intercourse. That means it’s unlikely that your size is at fault or you’re doing something “wrong.”
Penetration is not required stimulation for most women; instead, what they need is direct clitoral touch and stimulation, whether by hand, tongue, or vibrator. I’d recommend that you ask your wife what she prefers to feel pleasure and experience orgasm.
She may very well already know! The sooner you talk about it, the sooner you’ll both be more satisfied. If she’s not sure herself, she can do some exploration herself--or you can explore as a couple. And you can participate fully, knowing that your size doesn’t need to be an issue for either of you.
