Knowing that you are gay, will you still get yourself into marriage.
Build a family, and 10 -15 years down the road, cheats on your wife and be all guilty facing your kids ?
Though the deary wife might forgive and accepted you whole-heartedly, if you are given a chance to turn back time...how would you determine your future ?
Depending on the situation,
1. You are gay, and wife is a lesbian. I think it's perfectly fine to have a deal like that.
2. You are bi-sexual, and wife is perfectly straight. And arrangement you guys made prior the marriage commitment
3. You are plainly curious, and wifey says - hey, just go try it and confirm once and for all.
Taking off the just mentioned 3 scenarios and basing solely on the above "preface", I honestly think that the wife should be set free in order for you to live freely.
