i have beautiful wife, she has given so much sexual pleasure to me that sex has become very much dis-interesting for me with her (not her) i have started fantasying other womens when she has sex with me, so that i could get at least fake erection, i am looking for alternative sexual encounters nowadays, like fantasying bi sex, never done till date. looking for guys, is it wrong or what, i am damn confused

Plz do not take offence to this as i dont know u personally but u r married. That alone should be enough for u not to stray. At least tell ur wife how u feel, if things dont get any better then finish the relationship first before u engage in anything sexual, whether it be women or men. Its not fair on your wife for u to sleep with any1else. U must know this. Talk to her would be my advice, maybe not about the fantasies with men(or women) but just to see if u and her can work anything out(sexually, if this is your only issue in ur relationship) good luck!

totally agree with this ^^^

By your own admission she's a good wife. Don't treat her poorly.

I don't think you are bisexual, I think you are bi-curious. But I guarantee it is not worth your marriage. Be honest with your wife about what you are going thru. You owe her that and she does not deserve the pain of betrayal from you going out behind her back. Talk with her.
