one of my suprior officers is asking me to participate in a gay sex with him, like butt fucking etc, he once sucked my dick i was thrilled a lot. but i neither allowed him to fuck me nor i sucked him, but he desperately needs both. my question is that i am an unmarried if i do this with him, could i successfully enjoy with my wife in future

Go for it Bobby!! Being bi is like having the best of both worlds. I love sucking cock and taking it up the butt but, I also love eating pussy and fucking women. The answer is "Yes". Maybe you could both enjoy other men together.

Neil is right on saying "the best of both worlds".

I would say for sure go for it. BI is the best of everything. And if you cant find a woman who is ok with and into that or it is ok with her then she is the wrong woman for you.
