As I said as long as both can get satisfied by what one has....there is no need to do something that is unnatural. No need to play with nature....unless if it is really in need. We all do expect but it does not mean that needs to be accomplished just because other partner wants just not knowing the fact of the coming issues. However, this is not going to help in having a good relation (this might help in some phase of life but in reality it does not) if someone is looking for long-term relation. There are so many options in the market to get satisfied.....so why not look into this option rather than doing something that is unnatural and by the way, there are side effects.....and so many bad experience you hear now and then. Anyway....chill out...got to go....life is short to talk about this topic only.....! So get going!
