Hi Mark, There`s nothing wrong with your profile - its very nicely written - you sound honest and genuine. And your photos are good too ... you look like a nice family orientated man.
So, you doing nothing "wrong" - maybe its just that you are so young, and maybe you too good looking so you make the girls here a bit nervous of approaching you first? ..... Send some "flowers" to the ones you fancy.....?
Oh.. maybe one thing, in your profile you say you want to do other things on your weekends, "instead of getting drunk"..... I`d say leave that part out, about getting drunk, could come across giving the wrong impression of you? JMHO. Its okay for a young guy like you - imagine a 40yr old guy saying that? ....
