Yes the urges do get stronger as you get older, I think about it everyday! Wankluvr that is a fantasy for me! I love straight married guys.
I'm in a similar boat. Never been with a man but I did have one affair with another woman. Lately I've had strong urges, to the point of chatting and trading pics with other men online. I think the taboo is a big turn on. I've been fantasizing about playing with another cock in my hands and mouth and yes even getting face down / ass up for a man with a thick stiff cock to penetrate me, to fuck me and fill me with his semen.
...the only thing that slows down the urges is to face that you're bi...& go a head a & start sucking dicks...you'll feel better about yourself & you'll enjoy the sucking...especially if you swallow...
New here and i def have insight on this topic. Im married 15 years, had never thought of another man or found another man attractive. I started getting curious about transsexuals about 10 years ago and did it. It was amazing. My love and yearning for cock has opened me up to the point where i can say that although i am picky, i love certain guys and there are plenty of guys i now consider hot!! Cock itself is THE MOST addicting thing i have ever seen and my first love is still women and dont want a relationship with a guy but damm guys are sexy and i currently am hanging with a hot guy from time to time and actually invited him over when my wife was sleeping and sucked and swallowed him in my house. Sick rush. Btw swallowing cum is amazing
