I would also want to encourage you to be 'safe'....there are STD's that cause cervical cancer in women and are very hard to detect...men may not even show symptoms....they have a shot to prevent some but not all...condoms and spermacides are your best protection....not 100%...
When my H came home I did used condoms and spermacides until he finally went to the doctor and got a total STD panel done...I went with him to visit and follow-up so that I KNEW things were safe....the point I told him is IF he did have something he didn't know about and I got it...who would be raising our children???
I feel for you in having to share your H...I am not sure that would have worked for me...I know a couple of times I suggested to H that I wanted some intimacy....but he was still involved with her and not the type to try and keep up with 2 women...it was over a year after she was gone before he was intimate with me....it was still difficult to imagine...I had been his one and only when we married....after almost 28 years with him to know he shared himself with another was devistating for a long time...it still hurts 2.5 years later....
