First Time

I'm a straight looking and acting man, been married, lived with girlfriends, had long relationships with girls and, always sucked cock on the side. Over the last two years I've lost interest in girls. All I want is cock. First, it was just blowjobs, I give, and I've become damn good at it. I give head, the cock in my mouth cums and I swallow. That's usually the end of our transaction. But, I've been slowly wanting more. First I wanted to be fucked. It's grown to kissing, making out, foreplay just like with a woman, except I want the female role. We make out, undress, I kiss my way down to the cock, I suck it, lick it, and then give up my ass to be fucked.
Been fantasizing for probable a year. I watch gay porn, fuck my ass with a real feel cock dildo and imagine I'm the guy getting pounded. The dildo I use is high quality, 7 inches of dual density, real feel, looks so real, and I thought felt real. I can take all 7 inches with ease, no pain.
So, I've met a gay man, we've been seeing each other, but he was not into casual, blow and go sex. So we've dated and hung out, kissed and touched but did not go any further until this past weekend. I spent the night with him. Everything was just like I planned until I pulled his pants down, his cock was smaller than I wanted. Nothing like my 7 inch thick dildo. I give him maybe 5 and a half. Not thick either. I was a little disappointed. I sucked his cock with ease, and finished him swallowing every drop. He commented on what a fantastic blowjob. He returned the favor and gave me a great blowjob. We laid there for about 20 minutes talking, soon started kissing again. He got hard and I asked him to fuck me. I loved asking to be fucked, I said it several times and felt more feminine and slutty each time, and loved it. Here's where things get different, That small cock I mentioned, hurt the further in he pushed it. He was super hard, and was pointing straight up, he had to push it down to force it in me and every he pulled out to far it sprang up. pushing in beyond and inch or so met incredible resistance. Like it wouldn't go. If he pushed against it I could feel this pain deep inside me, almost a cramp. He was patient. He didn't force it, we took several breaks. Eventually he got all in. When he did he wrapped his arms around my waist, kissed my back and said "I'm all in".
He had to fuck me slowly, I couldn't take the hard pounding I've fantasized about. I was fucked slowly and gently, until he came in me. I said I was sorry I wasn't better and he said I would get used to it, the first time isn't always easy. I don't know why I can handle a larger dildo but a real cock was too much.
How long does it take to get broken in?
Also, I liked getting fucked. But it didn't feel very good. Just hurt, pressure and feeling like I had to poop. I'll do it again, just hope it gets beeter quick
