hi there!!
i was kinda against anal sex when i met my fiance!! but he was really into it, i think i was kinda nervous for the same reasons you were, i was sure it would hurt and i didnt know if id like it!! well me and him talked about it loads and he got the impression that i wanted to try it but was kinda scared!! one night when we were kinda fooling around on the bed he got behind me and started teasing my clit and everywhere else, the wetter i was getting he was spreading up to my ass!! i have to admit the feeling i was getting was REALLY good!! still, i thought he was just gonna do it doggy style....until that is...i felt his hard dick start to press against my ass!! this was my opportunity to tell him to stop...but i didnt!! i have to admit that i waited for the pain to come but i was quite relaxed and there was plenty of lubrication so it wasnt actually sore!! it can be a wee bit uncomfortable as he puts the head in but its not sore!! and this is really only the first time!! anyway, the pleasure you get during anal sex far outweighs the wee second of discomfort!! i would say give it a go!! if you dont like it then thats fine but at least you tried!! the more comfortable you get doing it you can possibly eve think about using a vibrator at the same time...(highly reccomended)
