Slammed

Hi Guys,
I'm still fairly new to all this. Got my Helix about 2 weeks ago and so far have only had 4 sessions. The first 3 were pleasant enough but nothing prepared me for #4. Now, I'm a staight guy, not even "bi curious", 53 years old and haven't done a lot of anal play in the past. I do however really enjoy feeling the Helix in me. In fact sometimes its kind of disappointing to take it out. I haven't experienced anything even close to what a Super O sounds like but last night was interesting to say the least. I think I had a few mini Os for the first time but having no real frame of reference, I'm not sure. When I first started I would start some contractions and eventually they would just start on their own. Until last night I would get a pleasant sensation in my prostate for few seconds but it wouldn't go beyond that. What I've found is I need to wait until that feeling starts and then really slow down, concentrate and almost tease myself until the pleasure starts to build. This happened a few times last night but I think I got too excited at the idea of success and couldn't hang on to it. The last time though was different. I got that tickling feeling and teased it along until I felt like I was about to cum and then started with some bigger contractions. Thats when something in me must have screamed F#@K ME. The Helix seemed to have a mind of its own. It started slamming into me hard, fast and deeper than I thought possible. I think it only lasted about 5 or 10 seconds, I'm really not sure but wow! I have kind of a hazy recolection of wishing it was bigger. It felt fantastic at the time but I must admit the bum is a little tender today. Anybody ever experience anything like this? I look forward to hearing from you.
