I concur with fudgester. Apparently, your boyfriend has
succumbed to the devil's whisper of lust, possibly due to the
foreign's soil he is residing, adopting the wrong culture.
Remember, we are Asian who have our own values and belief.
In a serious romantic relationship, heavy petting is considered
acceptable but not love making. That comes after you have signed
the dotted line at ROM. For more conservative type, perhaps after
customary wedding ceremony. Well, there are those who jumped into
husband-wife phase of relationship by doing the reverse. 
Unless your boyfriend has a strong spirituality, fudgester and
others' input are more or less the truth, nothing but the truth. Of
course, it is still your decision as we do not have a full picture
of your relationship. We are onlookers with limited perspective but
we know better because of our experience and knowledge of social
norm.
You are calling the shot at this point of time.
