RE: I am still a virgin and feel stuck. Should I have sex with a friend just to open mmyself up?

26 years and still a virgin that's great listen to the advantage you have that most women don't have, you don't have to do pap smear every three years or one year or even every six months if they notice abnormal cells which can lead to cervix cancer due to a active sex life or multiply sex partners. No unwanted pregnancy you don't even have to worry about sexual transmitted diseases, so yes if you choose not to have sex it's your business and no one else.
Take this thought to heart i had a cousin who never had sex at 25 years but due to friends and peer pressure she did,and the first and only man she ever slept with she contracted HIV and died within a year, so take this advice and ask the creator to bless you with a good husband. When your right partner comes all fear and anguish will go until then be true to your self .
