Is it normal to not know how to talk to cute women

Here's a trick, talk to them as if they were ugly. That way there's no pressure, and you won't have to use cheesy pick up lines. Just talk to her as if she was a friend.

If you see a pretty girl and want to go talk to her just tell her that you think she is attractive dont use a pick up line. But if you feel you need to use a pick up line try this..."If I could rearrange the alphabet...I would stick my dick up your ass."

Remember that this cute girl may have a shyness issue just like you, and that she probably doesn't feel pretty (like many women), so KingOfNowhere's advice is pretty good. Just tell her what you think of her

You should love and accept yourself, pretty girls like that.

I've been told I'm cute.
If you'd like to talk to me, a great way to do it would be to take a shower, put on some clean clothes and come compliment my car. :3

You don't need a pickup line at all.

Just don't try to look more smart & funny that you actualy are. Trying to compensate your lack of self-confidence just makes you look stupid. Any ordinary conversation starter might do it.

Cute girls are not aliens.

Be yourself. Hard as it is, dont concentrate on her. Keep your eyes up, dont stare at her chest. If your looking for a proper relationship out of it, i guess uhh... Be "different" dont give her the same silly chat up lines most guys give her. If shes with her friends say something like "Hello my name is [x] (shake their hands i guess) they should give theirs, say pleasure to meet you, try and win her friends over more than her in terms of friendship. Ask if you can borrow her for a minute and lead her away, then say "I just wanted to tell you i think your really adorable" (always smile, back straight, it gives the look of a confident man) try and do something a little fun i guess. If you just wanna bang her, "apparently" ignoring her, but listening to all of her friends (including her slightly) but you say comments to slightly lower her self-esteem, then she will vie for attention, say things like "wow shes a grabby one!" Or "You have the cutest bug's bunny overbite" almost accidental insult but not a hurtful one. Then when she tries to get your attention twice or more, then pay attention to her, then ask if you can talk privately after winging a few compliments and funny stories her way. Take it from there, although this is highly experimental, it worked for me twice out of three times i done it.

Usually the goal is her friends. Not her.
If shes on her own do what Anime7 said. But throw some wit in there with some humour and an odd compliment or two.

Thats my advice, but thats me. Might work differently.

Just do an internet search for "pua articles".
