I would suggest goin very slow. Having just barely, and I mean barely, gotten thru my own issues of insecurity and jealousy. Try very hard to always listen, even if it is the same issues. Not sure about your husband, but I have a very "bad" habit of over thinking everything. Try to be there for him. Its very hard for most men to deal with the insecurity of you wanting to have another love or lover. We as men usually start to thing that we are being replaced. So i would suggest lots of communication and patience. Good luck.
I would rather be hurt by your honest than pleasured by you lies!
