I am 19 years of age, and I love having sex with women older than me. Am I doing right or wrong?

Well, as people say age is just a number, it is just a number indeed. It is absolutely applicable in this case. As per my opinion, if you love her from the core of your heart, then age doesn’t matter. However, if you are just physically attracted towards her and using her for your sexual fulfillment, then it’s an offense. She has feelings too, so make sure that you don’t her in any way. However, both of you are friends-with-benefits, then the case is different. Both of you are enjoying each other’s company and want to keep things casual. Then it’s fine. Keep going!
