Anyone experience a freezing up around woman they find attractive and would like to approach?

For me, it just feels like danger ahead. almost like its wrong, no, that's not the right word.. more like bad/unacceptable/shameful for me to want intimacy, and a fear/shame of others knowing what I am up to. I still seem to have the need to keep this stuff secret even thought I know attraction/intimacy etc. is perfectly normal.

I just can't seem to feel even remotely comfortable around woman never mind get/have a girlfriend (think thats the worst part of it, wanting and being unable to get), Makes me feel inadequate as a man.
