Hi there,
Lol,im not from singapore but from malaysia so pretty close to where you live.Pretty normal to be skeptical but no harm in trying them out anyway.Im still pretty new to it myself so cant really confirm how effective it is but there are definitely effects.The people here are really helpful and friendly though anyway and answer questions really quickly.
You will get a 25$ gift certificate for your intro and 5$ rewards points when signing up so youll be able to get your first purchase more or less free anyway so its best to try it out and see if works for you.The link to the requirements for the gift certificate is below though think you just need to describe your personality a bit more to qualify and so that the experts will be able to recommend things for you better.

For the girlfriend,it would probably be best if the experts give you the advice since they are more experienced.If your looking for something to spice up the bedroom though,could probably try turn up the heat.
I recommend you read some of the following threads to get a better idea what some of the products do and will help you make a choice for your first purchase.
