OP I am on same page, and my age is way above 25. Well from my experience the reason why I failed so much is because of my personality being an introvert and having no good friends (boys) who understands or comfortable with to hang out. You better try to find some good friends (boys) who have no such issues and then try to hang out with him around girls to get yourself comfortable. Also keep your standards low and told yourself about it, and do not look at girls like they are special. Hope you find some luck in overcoming this as I could not even after trying. Wish you best! PS: DO NO GO AFTER RELATIONSHIPS RIGHT NOW SERIOUSLY, JUST AS YOU ARE TOO YOUNG. JUST GET FRIENDS TO HANG OUT.
