How can I tell my gurlfriend that I need to be hugged and cuddled more, without sounding wimpy?

Don't worry about sounding wimpy dude. If you really like your girlfriend you should be comfortable with her and not be afraid of her making you sound wimpy. Plus chicks like it when you sound romantic so like say it in a "I love it when you're in my arms." kind of way. Like your girl should see the strong boyfriend through the caring boyfriend as well remember no girl really wants a tool! So don't be afraid to open up to her dude!
