Is it normal to not be able to successfully have sex?

I have heard this from many people.

About 4. Maybe 3. Just keep trying maybe use some lube or something it's normal not to be able too

Although it's unlike, to rule out the possibility of anything clinically wrong with you (e.g. vagisimnus) you might try inserting something penis-sized yourself (if you never have before). If you can do that, you can have sex and it's probably just nerves.

Its completely normal. Finger yourself to stretch yourself out. Being really turned on helps too. My first gf was a virgin and I couldnt get it in her the first 3 times we tried to have sex.

Maybe he was too soft, maybe you weren't wet enough, maybe both. Sometimes the nervousness of it being your first time can overwhelm the situation and kill the mood. Just relax, have plenty of foreplay and try again :)

Jesus I feel like I'm a freshman in high school again....

The first time me and my gf did it there was a lot of build up first, we didn't use any fingers, just made sure she was really wet and she told me to just do it, even if it hurt her. At first it did, but then it felt good and now she loves it.

I had the same problem when I first tried when I was 17. Now, a year later, we are getting up our courage to try again. Arousal is the key here. Last time we were both too scared, and he wasn't rock hard, and I wasn't soaking wet...so for the first time, it was a no-go. Next time, make sure you're in a good setting--alone in a hotel room or something. Play out your pet fantasies as foreplay, until you are as wet and hot as can be. Then, spread your legs and let him take over. It will hurt. I know that much. He needs to be brave enough to proceed even if you are whimpering and squirming with pain. From what I hear, it'll all be great once that first time is over!
