Burning Sensation in Penis after spraying STUD 100, Could I have STD?

Dear Ask The Doctor: Almost three weeks ago i had sex with some girl, but before we had sex I used this STUD 100 for PE (i also sprayed it in excess). It was recomend to me by a friend. well After sex the stud 100 did not work because i lasted my usual time, everyone else ive talked to says its worked for them. but it never did for me. Its been almost three week and i still have a slight burning sensation, no pain when i urinate. Do you think its because I sprayed excess of the stud, or maybe ive got an STD. Am really worried. and also is there something wrong with me that the STUD did not work for me.

Dear Allen: I do understand your concern. Premature ejaculation at your age is most probably due to stress, anxiety and unrealistic expectations of performance and may not represent any underlying disease or problem.

STUD 100 contains lidocaine which is an anesthetic agent and may sometimes cause skin irritation and burning. You may need to do a urine test and bloodwork to exclude STD, which may also cause burning sensation.

I would advise against using STUD 100 in your case as you may have some allergic reaction to the drug. Also would advise you to practise safe sex by wearing condoms. Hope the information helps.
