Red bumps on penis shaft?

Hi there

I have been sexually active with my girlfriend for about 6 months and we haven't had any issues what so ever of this nature and we both do not have any sort of STD or STI.

A couple of days ago she shaved her bellow bits and soon after developed red bumps similar to mine, the next day after we had intercourse we both woke up with inflamed red bumps around our genitals 

Please could someone shed some light if possible as to what I/we could have?

 

Best to see a dermatologist asap , three possible diagnosis scabies , wart or molluscum contagiosum
