Maybe TMI but

What's everyone's thoughts on Anal sex exspically during pregnancy...me and my husband have been trying new things well he's been wanting to try anal for along time but I haven't done that ever so we have tried it a few times an most the time I can't get past the tip of his penis before I tell him stop.. Well I'm a submissive I like to be told what to do and for my husband to be in control only in the bedroom so I asked him to keep going this morning even if I ask him to stop and now I kinda like it once I got past the entry I guess you could say. But I'm not sure I like it because I'm pregnant and everything about him turns me on more lately or if I really actually like it......
