Sex... Please help a sister out :)

Ok ladies.. I need some help (embarrassing as it is).

I need ideas of how to come on to my man. I'm horrible at this :( I just don't know what to say or do (unless I'm drunk lol). I've always wanted to talk dirty to him but can never find the words. Can't even tell him what I want/need. He wants me to initiate it more but I get very shy. Probably cuz when I have in the past he rejected it and its embarrassing!! Idk if I did something wrong or he just wasn't in the mood but either way it didn't make me feel great about it. I want to try again, especially since being pregnant with my raging hormones make me want him every second of the day!! I can't get enough and he ain't giving it up enough.. Lol.

So if anyone could give me any ideas of how to talk to or touch him (other than just grabbing his junk and jumping on? Ha-ha).

We have been together for many years and enjoy rough sex and trying different things. I just don't get it why I can't just let go for my husband the way he wants me to and how I want to (without being under the influence). Thanks in advance :)
