My BF won't do oral on me!!!

Out of 3 years of a relationship my boyfriend hasnt done "it" on me but 1 time.....he's making me think its me even though U bathe at least 3 times a day and shave/wax every 3 weeks!!! When I asked him he said he had a bad experience in the past ?? He wants/loves for me to do "it" for him but wont return the favor for me!! Sex isnt everything but this is becoming a real problem for me...I even thought about having a woman on the side just for those purposes!!!
