Haven't had a orgasm from sex in 2 years. why?

Many variables: This might be a difficult question to answer. There could be many variables that include who your partner is and whether they know how to stimulate you in that manner. Not to judge but I hope you are using condoms and birth control a this young age. Teen pregnancy is a difficult road to travel.

It may take time: Sometimes it may take time to learn to have an orgasm. Also choice of partner and type of stimulation is important. Medication and certain neurological or psychological issues may block an orgasm. Always use protection.

Depends....: If you have trusted respectable relation ship.........without fear/apprehension.....you will have it. Mind and body is connected........you should discuss this with your partner( male ),Start in a relaxed quite comfortable place, ask him to spend little time for fore play. Further guidance as needed ..........

Not So Simple,Right?: The answer could get very technical and depends on what your unique needs are,how you respond, timing,environment,who you are with and,importantly, your state of mind(including your overall mindset,past experiences,upbringing,attitudes toward sex, philosophy-if you have one-and,again,more-most importantly who you are with and what he or she brings with them (exactly like you)So,get some counseling
