Is it normal that my wife did me with a strapon - and i liked it

To keep this short, my wife and I tried a little role reversal for fun and part of it was her taking me with a strap-on dildo. Even though it was my idea, I didn't think I would enjoy the penetration part, it was just part of the game.
It started off hurting a lot (the dildo was way to big - I had bought if for her some time back and she would never use it because of the size.) Aside from hurting, it took a long time for her to get it in, but when she did she got aggresive saying that since I thought it was a proper sized dildo for her that I was going to get the whole thing. Well I did, somewhat painfully, but then strangley, after it was all the way in, it started to feel a little good. Then after some more time and more lube, she, let's say, 'went to town on me' and I found myself wanting more and more. During some very deep thrusting, my body went into a convulsing orgasm and I shot copious amounts of semen 5 of 6 feet through the air onto the wall behind me.

Is this normal that I am totally not gay, but 'by far' the best orgasm of my life was achieved in this way. Since that night I can barely think of anything else. If she is not into this again, I don't know what I'll do?
