Just tell him! He will understand especially if its your first time.
If he is truly in love with you he will respect that and wait till you both are ready.
Simply state, "I am not ready for sex." If he truly cares about you, he will listen and respect your wishes. If he pressures you, he has only one interest in you; unload him and find the one you deserve.
If you truly like her, maybe you are willing to wait.
just sit him down and talk to him and just ask him nice and gentle if he is cheating on you. yes, he will probability get mad but if he truly loves you he would answer honestly and not over react.
If your boyfriend proposes marriage to you then you either love him enough to answer 'yes' (perhaps hug or kiss him and show how happy you are) or, if you have the slightest doubt you are not truly in love with him then say 'no' and let him know that you are not ready to commit at that moment.
ASK
You know if your truly in love with your boyfriend when he treats you like a queen and buys you outstanding and amazing stuff that you love!!!!!
you will know when your ready and when you want to
i cant
The answer depends on how truly contrite and trustworthy the boyfriend on never cheating.
Yes, if you love your boyfriend and he loves you truly. Then your boyfriend will not pressure you into anything, such as sex.
Just be honest, if he truly loves you it won't bother him and he will overlook it. It is not good to keep anything hidden like that during a good relationship.
