Sorry, but ur advice won't work for me.
You are saying that guys should bed their gf as soon as they have
one. But I believe that virginity is a very precious and sacred
thing a girl has. And if she gives it away so easily, that shows
how cheap she is.
No offence but I think that one should wait till after marriage
before bringing sex into the picture. I'm a guy, and I don't need
to bed my current gf to secure her love for me. I know I'm secured
enough and we are still very much in love with each other.
Having sex will not secure a relationship. Love does! Sex is only
part of the after-marriage relationship. If every guy thinks like
you do (having only sex in the mind without considering commitment,
love, faith, trust in a relationship etc) then sad to say, they
will eventually be in for a very painful and angry breakup, either
sooner or later.
Again, I have to stress, that people without maturity should NOT be
in a relationship. Not trying to give a lecture here but, since so
much had happened to me in the past and cos of my experiences, I'm
totally against pre-marital sex.
