Dear CAB readers: Should I engage in pre-marital sex?

From a female CAB reader

I have been dating a great guy for 6 months and he recently proposed.....I said Yes! The problem is that we have not made love, ( he is not gay oooo) we have been advised to stay away from pre-marital sex during counselling.

My boo is fine with it but I am worried because I have not tested our sexual compatibility. Please I need mature minds to advise me on whether to engage in premarital sex or not. This is really important to me. Thanks
