Wow, a profile in all caps, interesting.

First off, if he is mentioning sex in his profile, well it is really high up on his list of things he is looking for. Also saying that it will be "great" is a bit much, that is subjective anyway. Some might consider him great, others horrible, depends on the preferences of the person. In any case, he shouldn't be planning for that to happen for a while.

While it is true that guys typically fall in "love" more quickly than women (the physical condition of love) it isn't likely to happen that quickly.

I would guess that he is doing the same thing practiced by young teenage boys, saying it in the hopes that it will get you to think he is more committed. Usually nothing more than a ploy to try to get a woman out of her clothes. When a guy really means that he loves you there will be a difference, you will be able to tell. Or I hope so anyway, it might be a bit difficult with some, not really sure.
