Dear 19 year old,
I don,t think its a turn off it sometimes becomes more of a challenge to men and others its more that they can,t be bothered to be in relationship that perhaps does,nt offer them or have the potential for quick sex.
I remember a while back that a young girl around your age offered to sell her virginity on ebay and eventually did so much to the disgust of others however one women did reply and said tell you what at least she got something out of it rather than me who lost it to some spotty faced student in a bedsit who I never saw again.
So a couple of cases of different situations as for you your feelings are spot on when you say I,d like to get to know you a little better first I,d go further and say it will be just when I,m ready and not until!
If you loose some boyfriends because of the way you feel then so be it. Don,t give in under pressure
I can,t tell you when you should loose your virginity but I can tell you that you,ll never forget when you did.
Hold on to your reasons why, they are right
bon chance
