There is no substitute for the real thing. A real dick will feel much better especially if you are with an experienced top who cares about your pleasure. He should get you so aroused by caressing, kissing, rimming, sucking, that you will want his dick inside you more than anything else; and even if you feel a little pain at first, it will be pleasurable. For the beginner it may be best to start with you on top, that way you have control of how deep and how fast he goes inside you.
I can think of only one time when I didn't enjoy having a real dick inside me. Suffice it to say that I got myself in a (consensual) situation where I was the only bottom in a group of several men who hadn't had sex in a long time. I don't know how many there were total, I stopped counting after six, but I remember laying there wishing it would end.
I hope this helps.
