I'm guessing the lack of response previously is due to your use of the phrase "nice guy". this kind of sums it up.
The Difference Between a Nice Guy and a Good Man
To answer your question: I suppose it depends what you're looking for. If you're looking for sex, it might work (since you're a member of this site). If you're looking for a relationship, this would start things off on the wrong note.
I am a good woman. I am looking for a good man. An unsolicited dick pick would not work for me. When I'm on dating sites, I rarely get dick pics because of how I present myself... there are no suggestive photos, no innuendos, and I explicitly state that I am looking for monogamy. I think filters out a lot of the BS of people looking for hookups. Obvi by my being on this site, I've got a healthy attitude toward sex, but I don't lead with that because it's not what I want to build a relationship on. I see you've been around this site for years... if you've perused this forum and WI, you'll see that penis size ranks pretty low on the list of reasons we'd date a man. If all you have to offer is a big dick, I'm going to look elsewhere.
