help?

it sounds like you are going out with a very immature little girl who is a lil to cocky for her own good. if she doesnt relax she is going to end up pregnant. you need to be with stronger one and put her in her place, if you are both only 14 then its best you wait a few years before you do anything. And you'll appreciate it oher than ending up a 16yr old with a kid on the way. Be the mature one.

personally dont have sex until you are at least 16 because than you wont look werid buying a condom and she wont look werid going on birth control. If you both cant go get protected then you shouldnt have sex at all. Maybe she isnt the right one but you think it is becuase your only 14 and 14 yr olds are only horny and arent looking for a meaning relationship. Also you might suck at having sex than youll become an insecure guy and never get another girlfriend. So just wait.

14 is wayy to young to start having sex, and yes, it does ruin relationships at this age. You dont have sex because your horny!! Sex should be shared with someone you've been involved with for a long period of time. Someome you truly love(14 yr old dont know the true meaning of love) Someone whom you trust. Not because 2 teenagers hormones are raging!!
If it's truly love, and it's meant to be, it will survive and even grow stronger without sex. If it isn't, then you will be really glad you waited and found that out, before you got intimately involved on a physical level. In order for sex to be a good thing, you need two people who are mature enough to really love and trust each other.
Mas*urbat*on is the safest sex there is!
Sex vs. Love> Love is not based on sex>sex does not equal love
Having sex and being in love is not the same thing
Mature reationships are built on mutal trust and repect, having sex wont make a relationship work. Having sex to prove your love for someone is one of the worse mistakes anyone can make. sexual pressure is a sure sign that the motivation is LUST rather than LOVE!
Sex is no foundation for love. Thats why relationships based on sex dont last!
