Actually, it's not 'what is lexington steele' but, who. A famous porn actor with a HUGE penis in length and girth. I read your surgery post and so on to your questions.
yes, she is going to have a very hard time with that new penis of yours. length is one thing but something with that width, well, let's say that among the gay bottoms I know they would pause before trying to take that up their bums. You'll get a good reaction to how well she will like anal play if you rim the ass for a while with tongue and then start with one finger [clip those nails down] If and when she can handle 2-3 fingers, then you can take the time to lube up your dick, in a condom, and give it a try. Best postion is for her to sit on your dick and let her get used to it at her own speed. If you really, really want to try anal sex, I'd find a nice willing bottom male; they will know all the tricks to make it pleasureable for you. [this could make a good amateur video for some of those adult sites or cam sites] just a thought; make a little cash while you're experimenting with all this backdoor action.
