BF is so excited in having sex and I’m avoiding it at all costs

So I started having sex in 2014 but only had it once that year and then fast forward to 2018 I had sex again with this new guy (but only once in December).

So since I told him that I have only had sex once in my entire life, he keeps talking about that fact and how sex is great and blah blah blah.🗣🗣🗣

To be quiet honest, I’m not looking forward to having sex with him. Yeah I’m sure his great but I’m just avoiding sex.
