I started off just tip of tongue, but as I stretched more and messed around with my positioning, I've been able to get more and more in. I can now get the whole head in my mouth, and yes I sometimes cum and swallow a bit, just need to get used to it that's all. I'm 6', 180 lbs; my equipment is 8'' long and a shade under 6'' girth; I have to agree, it's all about flexibility, and especially stretching every day. Let me know if you want me to post my daily stretches. I'll try to post a picture or something soon.
