London, Feb 25 (IANS): Singer Nick Jonas says the “hardest part” of his career so far has been the focus on his sex life when he was a teenager in "The Jonas Brothers" and he wore a purity ring to signify he was celibate.

Addressing the Oxford University Union Monday night, the 22-year-old said it made him uncomfortable to have people commenting and making judgements about his bedroom behaviour when he was young, reports femalefirst.co.uk.

“Living your life in front of people is incredibly uncomfortable for many reasons. You go through your awkward stage at some point and...everybody's hair looks dumb and everybody thinks an Ed Hardy T-shirt is a good idea,” Jonas said.

“For me, the hardest part of all of it was the emphasis on sex and sex life and how at 13 or 14 years old and because of the detachment of seeing someone on TV or the computer it was okay to comment on a 13 or 14 year old's sex life.

“You wouldn't do that in a normal setting but because I'm living a public life as a celebrity (people did), that was hard. That became a big topic... we all went through a journey,” he added.

Nick starred in band The Jonas Brothers with his siblings Joe Jonas and Kevin Jonas several years ago and at the height of their popularity they became known for wearing purity rings to signify they were abstaining from sex.
