Intercourse issues

Ashlynn
So my boyfriend and I have been having sex since December. When we first started it was pretty painful for me and he was gentle and considerate towards my discomfort. Well It's March now, and we had sex today. I think it was close to a 7/8 out of 10 pain. I just sort of concealed it though. I didn't want to worry him or make him think that he wasn't satisfying. But I was just wondering why it hasn't started to be pleasurable. Could it be inadequate lubrication? Improper technique? I could really use some input. Should I buy some Pink© Lube? Please help!
